-This document provides an overview of the msm_gpiomux interface, which
-is used to provide gpio pin multiplexing and configuration on mach-msm
-targets.
-
-History
-=======
-
-The first-generation API for gpio configuration & multiplexing on msm
-is the function gpio_tlmm_config().  This function has a few notable
-shortcomings, which led to its deprecation and replacement by gpiomux:
-
-The 'disable' parameter:  Setting the second parameter to
-gpio_tlmm_config to GPIO_CFG_DISABLE tells the peripheral
-processor in charge of the subsystem to perform a look-up into a
-low-power table and apply the low-power/sleep setting for the pin.
-As the msm family evolved this became problematic. Not all pins
-have sleep settings, not all peripheral processors will accept requests
-to apply said sleep settings, and not all msm targets have their gpio
-subsystems managed by a peripheral processor. In order to get consistent
-behavior on all targets, drivers are forced to ignore this parameter,
-rendering it useless.
-
-The 'direction' flag: for all mux-settings other than raw-gpio (0),
-the output-enable bit of a gpio is hard-wired to a known
-input (usually VDD or ground).  For those settings, the direction flag
-is meaningless at best, and deceptive at worst.  In addition, using the
-direction flag to change output-enable (OE) directly can cause trouble in
-gpiolib, which has no visibility into gpio direction changes made
-in this way.  Direction control in gpio mode should be made through gpiolib.
-
-Key Features of gpiomux
-=======================
-
-- A consistent interface across all generations of msm.  Drivers can expect
-the same results on every target.
-- gpiomux plays nicely with gpiolib.  Functions that should belong to gpiolib
-are left to gpiolib and not duplicated here.  gpiomux is written with the
-intent that gpio_chips will call gpiomux reference-counting methods
-from their request() and free() hooks, providing full integration.
-- Tabular configuration.  Instead of having to call gpio_tlmm_config
-hundreds of times, gpio configuration is placed in a single table.
-- Per-gpio sleep.  Each gpio is individually reference counted, allowing only
-those lines which are in use to be put in high-power states.
-- 0 means 'do nothing': all flags are designed so that the default memset-zero
-equates to a sensible default of 'no configuration', preventing users
-from having to provide hundreds of 'no-op' configs for unused or
-unwanted lines.
-
-Usage
-=====
-
-To use gpiomux, provide configuration information for relevant gpio lines
-in the msm_gpiomux_configs table.  Since a 0 equates to "unconfigured",
-only those lines to be managed by gpiomux need to be specified.  Here
-is a completely fictional example:
-
-struct msm_gpiomux_config msm_gpiomux_configs[GPIOMUX_NGPIOS] = {
-	[12] = {
-		.active = GPIOMUX_VALID | GPIOMUX_DRV_8MA | GPIOMUX_FUNC_1,
-		.suspended = GPIOMUX_VALID | GPIOMUX_PULL_DOWN,
-	},
-	[34] = {
-		.suspended = GPIOMUX_VALID | GPIOMUX_PULL_DOWN,
-	},
-};
-
-To indicate that a gpio is in use, call msm_gpiomux_get() to increase
-its reference count.  To decrease the reference count, call msm_gpiomux_put().
-
-The effect of this configuration is as follows:
-
-When the system boots, gpios 12 and 34 will be initialized with their
-'suspended' configurations.  All other gpios, which were left unconfigured,
-will not be touched.
-
-When msm_gpiomux_get() is called on gpio 12 to raise its reference count
-above 0, its active configuration will be applied.  Since no other gpio
-line has a valid active configuration, msm_gpiomux_get() will have no
-effect on any other line.
-
-When msm_gpiomux_put() is called on gpio 12 or 34 to drop their reference
-count to 0, their suspended configurations will be applied.
-Since no other gpio line has a valid suspended configuration, no other
-gpio line will be effected by msm_gpiomux_put().  Since gpio 34 has no valid
-active configuration, this is effectively a no-op for gpio 34 as well,
-with one small caveat, see the section "About Output-Enable Settings".
-
-All of the GPIOMUX_VALID flags may seem like unnecessary overhead, but
-they address some important issues.  As unused entries (all those
-except 12 and 34) are zero-filled, gpiomux needs a way to distinguish
-the used fields from the unused.  In addition, the all-zero pattern
-is a valid configuration!  Therefore, gpiomux defines an additional bit
-which is used to indicate when a field is used.  This has the pleasant
-side-effect of allowing calls to msm_gpiomux_write to use '0' to indicate
-that a value should not be changed:
-
-  msm_gpiomux_write(0, GPIOMUX_VALID, 0);
-
-replaces the active configuration of gpio 0 with an all-zero configuration,
-but leaves the suspended configuration as it was.
-
-Static Configurations
-=====================
-
-To install a static configuration, which is applied at boot and does
-not change after that, install a configuration with a suspended component
-but no active component, as in the previous example:
-
-	[34] = {
-		.suspended = GPIOMUX_VALID | GPIOMUX_PULL_DOWN,
-	},
-
-The suspended setting is applied during boot, and the lack of any valid
-active setting prevents any other setting from being applied at runtime.
-If other subsystems attempting to access the line is a concern, one could
-*really* anchor the configuration down by calling msm_gpiomux_get on the
-line at initialization to move the line into active mode.  With the line
-held, it will never be re-suspended, and with no valid active configuration,
-no new configurations will be applied.
-
-But then, if having other subsystems grabbing for the line is truly a concern,
-it should be reserved with gpio_request instead, which carries an implicit
-msm_gpiomux_get.
-
-gpiomux and gpiolib
-===================
-
-It is expected that msm gpio_chips will call msm_gpiomux_get() and
-msm_gpiomux_put() from their request and free hooks, like this fictional
-example:
-
-static int request(struct gpio_chip *chip, unsigned offset)
-{
-        return msm_gpiomux_get(chip->base + offset);
-}
-
-static void free(struct gpio_chip *chip, unsigned offset)
-{
-        msm_gpiomux_put(chip->base + offset);
-}
-
-	...somewhere in a gpio_chip declaration...
-	.request = request,
-	.free    = free,
-
-This provides important functionality:
-- It guarantees that a gpio line will have its 'active' config applied
-  when the line is requested, and will not be suspended while the line
-  remains requested; and
-- It guarantees that gpio-direction settings from gpiolib behave sensibly.
-  See "About Output-Enable Settings."
-
-This mechanism allows for "auto-request" of gpiomux lines via gpiolib
-when it is suitable.  Drivers wishing more exact control are, of course,
-free to also use msm_gpiomux_set and msm_gpiomux_get.
-
-About Output-Enable Settings
-============================
-
-Some msm targets do not have the ability to query the current gpio
-configuration setting.  This means that changes made to the output-enable
-(OE) bit by gpiolib cannot be consistently detected and preserved by gpiomux.
-Therefore, when gpiomux applies a configuration setting, any direction
-settings which may have been applied by gpiolib are lost and the default
-input settings are re-applied.
-
-For this reason, drivers should not assume that gpio direction settings
-continue to hold if they free and then re-request a gpio.  This seems like
-common sense - after all, anybody could have obtained the line in the
-meantime - but it needs saying.
-
-This also means that calls to msm_gpiomux_write will reset the OE bit,
-which means that if the gpio line is held by a client of gpiolib and
-msm_gpiomux_write is called, the direction setting has been lost and
-gpiolib's internal state has been broken.
-Release gpio lines before reconfiguring them.

+ACPI Tables
+-----------
+The expectations of individual ACPI tables are discussed in the list that
+follows.
+
+If a section number is used, it refers to a section number in the ACPI
+specification where the object is defined.  If "Signature Reserved" is used,
+the table signature (the first four bytes of the table) is the only portion
+of the table recognized by the specification, and the actual table is defined
+outside of the UEFI Forum (see Section 5.2.6 of the specification).
+
+For ACPI on arm64, tables also fall into the following categories:
+
+       -- Required: DSDT, FADT, GTDT, MADT, MCFG, RSDP, SPCR, XSDT
+
+       -- Recommended: BERT, EINJ, ERST, HEST, SSDT
+
+       -- Optional: BGRT, CPEP, CSRT, DRTM, ECDT, FACS, FPDT, MCHI, MPST,
+          MSCT, RASF, SBST, SLIT, SPMI, SRAT, TCPA, TPM2, UEFI
+
+       -- Not supported: BOOT, DBG2, DBGP, DMAR, ETDT, HPET, IBFT, IVRS,
+          LPIT, MSDM, RSDT, SLIC, WAET, WDAT, WDRT, WPBT

+       Optional, not currently supported, but could be used on ARM if and
+       only if one uses the GPE_BIT field to represent an IRQ number, since
+       there are no GPE blocks defined in hardware reduced mode.  This would
+       need to be modified in the ACPI specification.
+
+EINJ   Section 18.6 (signature == "EINJ")
+       == Error Injection table ==
+       This table is very useful for testing platform response to error
+       conditions; it allows one to inject an error into the system as
+       if it had actually occurred.  However, this table should not be
+       shipped with a production system; it should be dynamically loaded
+       and executed with the ACPICA tools only during testing.
+
+ERST   Section 18.5 (signature == "ERST")
+       == Error Record Serialization Table ==
+       On a platform supports RAS, this table must be supplied if it is not
+       UEFI-based; if it is UEFI-based, this table may be supplied. When this
+       table is not present, UEFI run time service will be utilized to save
+       and retrieve hardware error information to and from a persistent store.
+
+ETDT   Signature Reserved (signature == "ETDT")
+       == Event Timer Description Table ==
+       Obsolete table, will not be supported.
+
+FACS   Section 5.2.10 (signature == "FACS")
+       == Firmware ACPI Control Structure ==
+       It is unlikely that this table will be terribly useful.  If it is
+       provided, the Global Lock will NOT be used since it is not part of
+       the hardware reduced profile, and only 64-bit address fields will
+       be considered valid.
+
+FADT   Section 5.2.9 (signature == "FACP")
+       == Fixed ACPI Description Table ==
+       Required for arm64.
+
+       The HW_REDUCED_ACPI flag must be set.  All of the fields that are
+       to be ignored when HW_REDUCED_ACPI is set are expected to be set to
+       zero.
+
+       If an FACS table is provided, the X_FIRMWARE_CTRL field is to be
+       used, not FIRMWARE_CTRL.
+
+       If PSCI is used (as is recommended), make sure that ARM_BOOT_ARCH is
+       filled in properly -- that the PSCI_COMPLIANT flag is set and that
+       PSCI_USE_HVC is set or unset as needed (see table 5-37).
+
+       For the DSDT that is also required, the X_DSDT field is to be used,
+       not the DSDT field.
+
+FPDT   Section 5.2.23 (signature == "FPDT")
+       == Firmware Performance Data Table ==
+       Optional, not currently supported.
+
+GTDT   Section 5.2.24 (signature == "GTDT")
+       == Generic Timer Description Table ==
+       Required for arm64.
+
+HEST   Section 18.3.2 (signature == "HEST")
+       == Hardware Error Source Table ==
+       Until further error source types are defined, use only types 6 (AER
+       Root Port), 7 (AER Endpoint), 8 (AER Bridge), or 9 (Generic Hardware
+       Error Source).  Firmware first error handling is possible if and only
+       if Trusted Firmware is being used on arm64.
+
+       Must be supplied if RAS support is provided by the platform.  It
+       is recommended this table be supplied.
+
+HPET   Signature Reserved (signature == "HPET")
+       == High Precision Event timer Table ==
+       x86 only table, will not be supported.
+
+IBFT   Signature Reserved (signature == "IBFT")

+       x86_64 (AMD) only table, will not be supported.
+
+LPIT   Signature Reserved (signature == "LPIT")
+       == Low Power Idle Table ==
+       x86 only table as of ACPI 5.1; future versions have been adapted for
+       use with ARM and will be recommended in order to support ACPI power
+       management.
+
+MADT   Section 5.2.12 (signature == "APIC")
+       == Multiple APIC Description Table ==
+       Required for arm64.  Only the GIC interrupt controller structures
+       should be used (types 0xA - 0xE).
+
+MCFG   Signature Reserved (signature == "MCFG")
+       == Memory-mapped ConFiGuration space ==
+       If the platform supports PCI/PCIe, an MCFG table is required.
+
+MCHI   Signature Reserved (signature == "MCHI")
+       == Management Controller Host Interface table ==
+       Optional, not currently supported.
+

+       Optional, not currently supported.
+
+RSDP   Section 5.2.5 (signature == "RSD PTR")
+       == Root System Description PoinTeR ==
+       Required for arm64.
+
+RSDT   Section 5.2.7 (signature == "RSDT")
+       == Root System Description Table ==
+       Since this table can only provide 32-bit addresses, it is deprecated
+       on arm64, and will not be used.
+
+SBST   Section 5.2.14 (signature == "SBST")
+       == Smart Battery Subsystem Table ==
+       Optional, not currently supported.
+
+SLIC   Signature Reserved (signature == "SLIC")

+       == System Resource Affinity Table ==
+       Optional, but if used, only the GICC Affinity structures are read.
+       To support NUMA, this table is required.
+
+SSDT   Section 5.2.11.2 (signature == "SSDT")
+       == Secondary System Description Table ==
+       These tables are a continuation of the DSDT; these are recommended
+       for use with devices that can be added to a running system, but can
+       also serve the purpose of dividing up device descriptions into more
+       manageable pieces.
+
+       An SSDT can only ADD to the ACPI namespace.  It cannot modify or
+       replace existing device descriptions already in the namespace.
+
+       These tables are optional, however.  ACPI tables should contain only
+       one DSDT but can contain many SSDTs.
+
+TCPA   Signature Reserved (signature == "TCPA")
+       == Trusted Computing Platform Alliance table ==
+       Optional, not currently supported, and may need changes to fully
+       interoperate with arm64.
+
+TPM2   Signature Reserved (signature == "TPM2")
+       == Trusted Platform Module 2 table ==

+
+ACPI Objects
+------------
+The expectations on individual ACPI objects are discussed in the list that
+follows:
+
+Name   Section         Usage for ARMv8 Linux
+----   ------------    -------------------------------------------------
+_ADR   6.1.1           Use as needed.
+
+_BBN   6.5.5           Use as needed; PCI-specific.
+
+_BDN   6.5.3           Optional; not likely to be used on arm64.
+
+_CCA   6.2.17          This method should be defined for all bus masters
+                       on arm64.  While cache coherency is assumed, making
+                       it explicit ensures the kernel will set up DMA as
+                       it should.
+
+_CDM   6.2.1           Optional, to be used only for processor devices.
+
+_CID   6.1.2           Use as needed.
+
+_CLS   6.1.3           Use as needed.
+
+_CRS   6.2.2           Required on arm64.
+
+_DCK   6.5.2           Optional; not likely to be used on arm64.
+
+_DDN   6.1.4           This field can be used for a device name.  However,
+                       it is meant for DOS device names (e.g., COM1), so be
+                       careful of its use across OSes.
+
+_DEP   6.5.8           Use as needed.
+
+_DIS   6.2.3           Optional, for power management use.
+
+_DLM   5.7.5           Optional.
+
+_DMA   6.2.4           Optional.
+
+_DSD   6.2.5           To be used with caution.  If this object is used, try
+                       to use it within the constraints already defined by the
+                       Device Properties UUID.  Only in rare circumstances
+                       should it be necessary to create a new _DSD UUID.
+
+                       In either case, submit the _DSD definition along with
+                       any driver patches for discussion, especially when
+                       device properties are used.  A driver will not be
+                       considered complete without a corresponding _DSD
+                       description.  Once approved by kernel maintainers,
+                       the UUID or device properties must then be registered
+                       with the UEFI Forum; this may cause some iteration as
+                       more than one OS will be registering entries.
+
+_DSM                   Do not use this method.  It is not standardized, the
+                       return values are not well documented, and it is
+                       currently a frequent source of error.
+
+_DSW   7.2.1           Use as needed; power management specific.
+
+_EDL   6.3.1           Optional.
+
+_EJD   6.3.2           Optional.
+
+_EJx   6.3.3           Optional.
+
+_FIX   6.2.7           x86 specific, not used on arm64.
+
+\_GL   5.7.1           This object is not to be used in hardware reduced
+                       mode, and therefore should not be used on arm64.
+
+_GLK   6.5.7           This object requires a global lock be defined; there
+                       is no global lock on arm64 since it runs in hardware
+                       reduced mode.  Hence, do not use this object on arm64.
+
+\_GPE  5.3.1           This namespace is for x86 use only.  Do not use it
+                       on arm64.
+
+_GSB   6.2.7           Optional.
+
+_HID   6.1.5           Use as needed.  This is the primary object to use in
+                       device probing, though _CID and _CLS may also be used.
+
+_HPP   6.2.8           Optional, PCI specific.
+
+_HPX   6.2.9           Optional, PCI specific.
+
+_HRV   6.1.6           Optional, use as needed to clarify device behavior; in
+                       some cases, this may be easier to use than _DSD.
+
+_INI   6.5.1           Not required, but can be useful in setting up devices
+                       when UEFI leaves them in a state that may not be what
+                       the driver expects before it starts probing.
+
+_IRC   7.2.15          Use as needed; power management specific.
+
+_LCK   6.3.4           Optional.
+
+_MAT   6.2.10          Optional; see also the MADT.
+
+_MLS   6.1.7           Optional, but highly recommended for use in
+                       internationalization.
+
+_OFF   7.1.2           It is recommended to define this method for any device
+                       that can be turned on or off.
+
+_ON    7.1.3           It is recommended to define this method for any device
+                       that can be turned on or off.
+
+\_OS   5.7.3           This method will return "Linux" by default (this is
+                       the value of the macro ACPI_OS_NAME on Linux).  The
+                       command line parameter acpi_os=<string> can be used
+                       to set it to some other value.
+
+_OSC   6.2.11          This method can be a global method in ACPI (i.e.,
+                       \_SB._OSC), or it may be associated with a specific
+                       device (e.g., \_SB.DEV0._OSC), or both.  When used
+                       as a global method, only capabilities published in
+                       the ACPI specification are allowed.  When used as
+                       a device-specific method, the process described for
+                       using _DSD MUST be used to create an _OSC definition;
+                       out-of-process use of _OSC is not allowed.  That is,
+                       submit the device-specific _OSC usage description as
+                       part of the kernel driver submission, get it approved
+                       by the kernel community, then register it with the
+                       UEFI Forum.
+
+\_OSI  5.7.2           Deprecated on ARM64.  Any invocation of this method
+                       will print a warning on the console and return false.
+                       That is, as far as ACPI firmware is concerned, _OSI
+                       cannot be used to determine what sort of system is
+                       being used or what functionality is provided.  The
+                       _OSC method is to be used instead.
+
+_OST   6.3.5           Optional.
+
+_PDC   8.4.1           Deprecated, do not use on arm64.
+
+\_PIC  5.8.1           The method should not be used.  On arm64, the only
+                       interrupt model available is GIC.
+
+_PLD   6.1.8           Optional.
+
+\_PR   5.3.1           This namespace is for x86 use only on legacy systems.
+                       Do not use it on arm64.
+
+_PRS   6.2.12          Optional.
+
+_PRT   6.2.13          Required as part of the definition of all PCI root
+                       devices.
+
+_PRW   7.2.13          Use as needed; power management specific.
+
+_PRx   7.2.8-11        Use as needed; power management specific.  If _PR0 is
+                       defined, _PR3 must also be defined.

+_PSE   7.2.7           Use as needed; power management specific.
+
+_PSW   7.2.14          Use as needed; power management specific.
+
+_PSx   7.2.2-5         Use as needed; power management specific.  If _PS0 is
+                       defined, _PS3 must also be defined.  If clocks or
+                       regulators need adjusting to be consistent with power
+                       usage, change them in these methods.
+
+\_PTS  7.3.1           Use as needed; power management specific.
+
+_PXM   6.2.14          Optional.
+
+_REG   6.5.4           Use as needed.
+
+\_REV  5.7.4           Always returns the latest version of ACPI supported.
+
+_RMV   6.3.6           Optional.
+
+\_SB   5.3.1           Required on arm64; all devices must be defined in this
+                       namespace.
+
+_SEG   6.5.6           Use as needed; PCI-specific.
+
+\_SI   5.3.1,          Optional.
+       9.1

+_SLI   6.2.15          Optional; recommended when SLIT table is in use.
+
+_STA   6.3.7,          It is recommended to define this method for any device
+       7.1.4           that can be turned on or off.
+
+_SRS   6.2.16          Optional; see also _PRS.
+
+_STR   6.1.10          Recommended for conveying device names to end users;
+                       this is preferred over using _DDN.
+
+_SUB   6.1.9           Use as needed; _HID or _CID are preferred.
+
+_SUN   6.1.11          Optional.

+
+_SWS   7.3.3           Use as needed; power management specific; this may
+                       require specification changes for use on arm64.
+
+\_TTS  7.3.4           Use as needed; power management specific.
+
+\_TZ   5.3.1           Optional.
+
+_UID   6.1.12          Recommended for distinguishing devices of the same
+                       class; define it if at all possible.
+
+\_WAK  7.3.5           Use as needed; power management specific.
+
+
+ACPI Event Model
+----------------
+Do not use GPE block devices; these are not supported in the hardware reduced
+profile used by arm64.  Since there are no GPE blocks defined for use on ARM
+platforms, GPIO-signaled interrupts should be used for creating system events.
+
+
+ACPI Processor Control
+----------------------
+Section 8 of the ACPI specification is currently undergoing change that
+should be completed in the 6.0 version of the specification.  Processor
+performance control will be handled differently for arm64 at that point
+in time.  Processor aggregator devices (section 8.5) will not be used,
+for example, but another similar mechanism instead.
+
+While UEFI constrains what we can say until the release of 6.0, it is
+recommended that CPPC (8.4.5) be used as the primary model.  This will
+still be useful into the future.  C-states and P-states will still be
+provided, but most of the current design work appears to favor CPPC.
+
+Further, it is essential that the ARMv8 SoC provide a fully functional
+implementation of PSCI; this will be the only mechanism supported by ACPI
+to control CPU power state (including secondary CPU booting).
+
+More details will be provided on the release of the ACPI 6.0 specification.
+
+
+ACPI System Address Map Interfaces
+----------------------------------
+In Section 15 of the ACPI specification, several methods are mentioned as
+possible mechanisms for conveying memory resource information to the kernel.
+For arm64, we will only support UEFI for booting with ACPI, hence the UEFI
+GetMemoryMap() boot service is the only mechanism that will be used.
+
+
+ACPI Platform Error Interfaces (APEI)
+-------------------------------------
+The APEI tables supported are described above.
+
+APEI requires the equivalent of an SCI and an NMI on ARMv8.  The SCI is used
+to notify the OSPM of errors that have occurred but can be corrected and the
+system can continue correct operation, even if possibly degraded.  The NMI is
+used to indicate fatal errors that cannot be corrected, and require immediate
+attention.
+
+Since there is no direct equivalent of the x86 SCI or NMI, arm64 handles
+these slightly differently.  The SCI is handled as a normal GPIO-signaled
+interrupt; given that these are corrected (or correctable) errors being
+reported, this is sufficient.  The NMI is emulated as the highest priority
+GPIO-signaled interrupt possible.  This implies some caution must be used
+since there could be interrupts at higher privilege levels or even interrupts
+at the same priority as the emulated NMI.  In Linux, this should not be the
+case but one should be aware it could happen.
+
+
+ACPI Objects Not Supported on ARM64
+-----------------------------------
+While this may change in the future, there are several classes of objects
+that can be defined, but are not currently of general interest to ARM servers.
+
+These are not supported:
+
+       -- Section 9.2: ambient light sensor devices
+
+       -- Section 9.3: battery devices
+
+       -- Section 9.4: lids (e.g., laptop lids)
+
+       -- Section 9.8.2: IDE controllers
+
+       -- Section 9.9: floppy controllers
+
+       -- Section 9.10: GPE block devices
+
+       -- Section 9.15: PC/AT RTC/CMOS devices
+
+       -- Section 9.16: user presence detection devices
+
+       -- Section 9.17: I/O APIC devices; all GICs must be enumerable via MADT
+
+       -- Section 9.18: time and alarm devices (see 9.15)
+
+
+ACPI Objects Not Yet Implemented
+--------------------------------
+While these objects have x86 equivalents, and they do make some sense in ARM
+servers, there is either no hardware available at present, or in some cases
+there may not yet be a non-ARM implementation.  Hence, they are currently not
+implemented though that may change in the future.
+
+Not yet implemented are:
+
+       -- Section 10: power source and power meter devices
+
+       -- Section 11: thermal management
+
+       -- Section 12: embedded controllers interface
+
+       -- Section 13: SMBus interfaces
+
+       -- Section 17: NUMA support (prototypes have been submitted for
+          review)

+ACPI on ARMv8 Servers
+---------------------
+ACPI can be used for ARMv8 general purpose servers designed to follow
+the ARM SBSA (Server Base System Architecture) [0] and SBBR (Server
+Base Boot Requirements) [1] specifications.  Please note that the SBBR
+can be retrieved simply by visiting [1], but the SBSA is currently only
+available to those with an ARM login due to ARM IP licensing concerns.
+
+The ARMv8 kernel implements the reduced hardware model of ACPI version
+5.1 or later.  Links to the specification and all external documents
+it refers to are managed by the UEFI Forum.  The specification is
+available at http://www.uefi.org/specifications and documents referenced
+by the specification can be found via http://www.uefi.org/acpi.
+
+If an ARMv8 system does not meet the requirements of the SBSA and SBBR,
+or cannot be described using the mechanisms defined in the required ACPI
+specifications, then ACPI may not be a good fit for the hardware.
+
+While the documents mentioned above set out the requirements for building
+industry-standard ARMv8 servers, they also apply to more than one operating
+system.  The purpose of this document is to describe the interaction between
+ACPI and Linux only, on an ARMv8 system -- that is, what Linux expects of
+ACPI and what ACPI can expect of Linux.
+
+
+Why ACPI on ARM?
+----------------
+Before examining the details of the interface between ACPI and Linux, it is
+useful to understand why ACPI is being used.  Several technologies already
+exist in Linux for describing non-enumerable hardware, after all.  In this
+section we summarize a blog post [2] from Grant Likely that outlines the
+reasoning behind ACPI on ARMv8 servers.  Actually, we snitch a good portion
+of the summary text almost directly, to be honest.
+
+The short form of the rationale for ACPI on ARM is:
+
+-- ACPI’s bytecode (AML) allows the platform to encode hardware behavior,
+   while DT explicitly does not support this.  For hardware vendors, being
+   able to encode behavior is a key tool used in supporting operating
+   system releases on new hardware.
+
+-- ACPI’s OSPM defines a power management model that constrains what the
+   platform is allowed to do into a specific model, while still providing
+   flexibility in hardware design.
+
+-- In the enterprise server environment, ACPI has established bindings (such
+   as for RAS) which are currently used in production systems.  DT does not.
+   Such bindings could be defined in DT at some point, but doing so means ARM
+   and x86 would end up using completely different code paths in both firmware
+   and the kernel.
+
+-- Choosing a single interface to describe the abstraction between a platform
+   and an OS is important.  Hardware vendors would not be required to implement
+   both DT and ACPI if they want to support multiple operating systems.  And,
+   agreeing on a single interface instead of being fragmented into per OS
+   interfaces makes for better interoperability overall.
+
+-- The new ACPI governance process works well and Linux is now at the same
+   table as hardware vendors and other OS vendors.  In fact, there is no
+   longer any reason to feel that ACPI is only belongs to Windows or that
+   Linux is in any way secondary to Microsoft in this arena.  The move of
+   ACPI governance into the UEFI forum has significantly opened up the
+   specification development process, and currently, a large portion of the
+   changes being made to ACPI is being driven by Linux.
+
+Key to the use of ACPI is the support model.  For servers in general, the
+responsibility for hardware behaviour cannot solely be the domain of the
+kernel, but rather must be split between the platform and the kernel, in
+order to allow for orderly change over time.  ACPI frees the OS from needing
+to understand all the minute details of the hardware so that the OS doesn’t
+need to be ported to each and every device individually.  It allows the
+hardware vendors to take responsibility for power management behaviour without
+depending on an OS release cycle which is not under their control.
+
+ACPI is also important because hardware and OS vendors have already worked
+out the mechanisms for supporting a general purpose computing ecosystem.  The
+infrastructure is in place, the bindings are in place, and the processes are
+in place.  DT does exactly what Linux needs it to when working with vertically
+integrated devices, but there are no good processes for supporting what the
+server vendors need.  Linux could potentially get there with DT, but doing so
+really just duplicates something that already works.  ACPI already does what
+the hardware vendors need, Microsoft won’t collaborate on DT, and hardware
+vendors would still end up providing two completely separate firmware
+interfaces -- one for Linux and one for Windows.
+
+
+Kernel Compatibility
+--------------------
+One of the primary motivations for ACPI is standardization, and using that
+to provide backward compatibility for Linux kernels.  In the server market,
+software and hardware are often used for long periods.  ACPI allows the
+kernel and firmware to agree on a consistent abstraction that can be
+maintained over time, even as hardware or software change.  As long as the
+abstraction is supported, systems can be updated without necessarily having
+to replace the kernel.
+
+When a Linux driver or subsystem is first implemented using ACPI, it by
+definition ends up requiring a specific version of the ACPI specification
+-- it's baseline.  ACPI firmware must continue to work, even though it may
+not be optimal, with the earliest kernel version that first provides support
+for that baseline version of ACPI.  There may be a need for additional drivers,
+but adding new functionality (e.g., CPU power management) should not break
+older kernel versions.  Further, ACPI firmware must also work with the most
+recent version of the kernel.
+
+
+Relationship with Device Tree
+-----------------------------
+ACPI support in drivers and subsystems for ARMv8 should never be mutually
+exclusive with DT support at compile time.
+
+At boot time the kernel will only use one description method depending on
+parameters passed from the bootloader (including kernel bootargs).
+
+Regardless of whether DT or ACPI is used, the kernel must always be capable
+of booting with either scheme (in kernels with both schemes enabled at compile
+time).
+
+
+Booting using ACPI tables
+-------------------------
+The only defined method for passing ACPI tables to the kernel on ARMv8
+is via the UEFI system configuration table.  Just so it is explicit, this
+means that ACPI is only supported on platforms that boot via UEFI.
+
+When an ARMv8 system boots, it can either have DT information, ACPI tables,
+or in some very unusual cases, both.  If no command line parameters are used,
+the kernel will try to use DT for device enumeration; if there is no DT
+present, the kernel will try to use ACPI tables, but only if they are present.
+In neither is available, the kernel will not boot.  If acpi=force is used
+on the command line, the kernel will attempt to use ACPI tables first, but
+fall back to DT if there are no ACPI tables present.  The basic idea is that
+the kernel will not fail to boot unless it absolutely has no other choice.
+
+Processing of ACPI tables may be disabled by passing acpi=off on the kernel
+command line; this is the default behavior.
+
+In order for the kernel to load and use ACPI tables, the UEFI implementation
+MUST set the ACPI_20_TABLE_GUID to point to the RSDP table (the table with
+the ACPI signature "RSD PTR ").  If this pointer is incorrect and acpi=force
+is used, the kernel will disable ACPI and try to use DT to boot instead; the
+kernel has, in effect, determined that ACPI tables are not present at that
+point.
+
+If the pointer to the RSDP table is correct, the table will be mapped into
+the kernel by the ACPI core, using the address provided by UEFI.
+
+The ACPI core will then locate and map in all other ACPI tables provided by
+using the addresses in the RSDP table to find the XSDT (eXtended System
+Description Table).  The XSDT in turn provides the addresses to all other
+ACPI tables provided by the system firmware; the ACPI core will then traverse
+this table and map in the tables listed.
+
+The ACPI core will ignore any provided RSDT (Root System Description Table).
+RSDTs have been deprecated and are ignored on arm64 since they only allow
+for 32-bit addresses.
+
+Further, the ACPI core will only use the 64-bit address fields in the FADT
+(Fixed ACPI Description Table).  Any 32-bit address fields in the FADT will
+be ignored on arm64.
+
+Hardware reduced mode (see Section 4.1 of the ACPI 5.1 specification) will
+be enforced by the ACPI core on arm64.  Doing so allows the ACPI core to
+run less complex code since it no longer has to provide support for legacy
+hardware from other architectures.  Any fields that are not to be used for
+hardware reduced mode must be set to zero.
+
+For the ACPI core to operate properly, and in turn provide the information
+the kernel needs to configure devices, it expects to find the following
+tables (all section numbers refer to the ACPI 5.1 specfication):
+
+    -- RSDP (Root System Description Pointer), section 5.2.5
+
+    -- XSDT (eXtended System Description Table), section 5.2.8
+
+    -- FADT (Fixed ACPI Description Table), section 5.2.9
+
+    -- DSDT (Differentiated System Description Table), section
+       5.2.11.1
+
+    -- MADT (Multiple APIC Description Table), section 5.2.12
+
+    -- GTDT (Generic Timer Description Table), section 5.2.24
+
+    -- If PCI is supported, the MCFG (Memory mapped ConFiGuration
+       Table), section 5.2.6, specifically Table 5-31.
+
+If the above tables are not all present, the kernel may or may not be
+able to boot properly since it may not be able to configure all of the
+devices available.
+
+
+ACPI Detection
+--------------
+Drivers should determine their probe() type by checking for a null
+value for ACPI_HANDLE, or checking .of_node, or other information in
+the device structure.  This is detailed further in the "Driver
+Recommendations" section.
+
+In non-driver code, if the presence of ACPI needs to be detected at
+runtime, then check the value of acpi_disabled. If CONFIG_ACPI is not
+set, acpi_disabled will always be 1.
+
+
+Device Enumeration
+------------------
+Device descriptions in ACPI should use standard recognized ACPI interfaces.
+These may contain less information than is typically provided via a Device
+Tree description for the same device.  This is also one of the reasons that
+ACPI can be useful -- the driver takes into account that it may have less
+detailed information about the device and uses sensible defaults instead.
+If done properly in the driver, the hardware can change and improve over
+time without the driver having to change at all.
+
+Clocks provide an excellent example.  In DT, clocks need to be specified
+and the drivers need to take them into account.  In ACPI, the assumption
+is that UEFI will leave the device in a reasonable default state, including
+any clock settings.  If for some reason the driver needs to change a clock
+value, this can be done in an ACPI method; all the driver needs to do is
+invoke the method and not concern itself with what the method needs to do
+to change the clock.  Changing the hardware can then take place over time
+by changing what the ACPI method does, and not the driver.
+
+In DT, the parameters needed by the driver to set up clocks as in the example
+above are known as "bindings"; in ACPI, these are known as "Device Properties"
+and provided to a driver via the _DSD object.
+
+ACPI tables are described with a formal language called ASL, the ACPI
+Source Language (section 19 of the specification).  This means that there
+are always multiple ways to describe the same thing -- including device
+properties.  For example, device properties could use an ASL construct
+that looks like this: Name(KEY0, "value0").  An ACPI device driver would
+then retrieve the value of the property by evaluating the KEY0 object.
+However, using Name() this way has multiple problems: (1) ACPI limits
+names ("KEY0") to four characters unlike DT; (2) there is no industry
+wide registry that maintains a list of names, minimzing re-use; (3)
+there is also no registry for the definition of property values ("value0"),
+again making re-use difficult; and (4) how does one maintain backward
+compatibility as new hardware comes out?  The _DSD method was created
+to solve precisely these sorts of problems; Linux drivers should ALWAYS
+use the _DSD method for device properties and nothing else.
+
+The _DSM object (ACPI Section 9.14.1) could also be used for conveying
+device properties to a driver.  Linux drivers should only expect it to
+be used if _DSD cannot represent the data required, and there is no way
+to create a new UUID for the _DSD object.  Note that there is even less
+regulation of the use of _DSM than there is of _DSD.  Drivers that depend
+on the contents of _DSM objects will be more difficult to maintain over
+time because of this; as of this writing, the use of _DSM is the cause
+of quite a few firmware problems and is not recommended.
+
+Drivers should look for device properties in the _DSD object ONLY; the _DSD
+object is described in the ACPI specification section 6.2.5, but this only
+describes how to define the structure of an object returned via _DSD, and
+how specific data structures are defined by specific UUIDs.  Linux should
+only use the _DSD Device Properties UUID [5]:
+
+   -- UUID: daffd814-6eba-4d8c-8a91-bc9bbf4aa301
+
+   -- http://www.uefi.org/sites/default/files/resources/_DSD-device-properties-UUID.pdf
+
+The UEFI Forum provides a mechanism for registering device properties [4]
+so that they may be used across all operating systems supporting ACPI.
+Device properties that have not been registered with the UEFI Forum should
+not be used.
+
+Before creating new device properties, check to be sure that they have not
+been defined before and either registered in the Linux kernel documentation
+as DT bindings, or the UEFI Forum as device properties.  While we do not want
+to simply move all DT bindings into ACPI device properties, we can learn from
+what has been previously defined.
+
+If it is necessary to define a new device property, or if it makes sense to
+synthesize the definition of a binding so it can be used in any firmware,
+both DT bindings and ACPI device properties for device drivers have review
+processes.  Use them both.  When the driver itself is submitted for review
+to the Linux mailing lists, the device property definitions needed must be
+submitted at the same time.  A driver that supports ACPI and uses device
+properties will not be considered complete without their definitions.  Once
+the device property has been accepted by the Linux community, it must be
+registered with the UEFI Forum [4], which will review it again for consistency
+within the registry.  This may require iteration.  The UEFI Forum, though,
+will always be the canonical site for device property definitions.
+
+It may make sense to provide notice to the UEFI Forum that there is the
+intent to register a previously unused device property name as a means of
+reserving the name for later use.  Other operating system vendors will
+also be submitting registration requests and this may help smooth the
+process.
+
+Once registration and review have been completed, the kernel provides an
+interface for looking up device properties in a manner independent of
+whether DT or ACPI is being used.  This API should be used [6]; it can
+eliminate some duplication of code paths in driver probing functions and
+discourage divergence between DT bindings and ACPI device properties.
+
+
+Programmable Power Control Resources
+------------------------------------
+Programmable power control resources include such resources as voltage/current
+providers (regulators) and clock sources.
+
+With ACPI, the kernel clock and regulator framework is not expected to be used
+at all.
+
+The kernel assumes that power control of these resources is represented with
+Power Resource Objects (ACPI section 7.1).  The ACPI core will then handle
+correctly enabling and disabling resources as they are needed.  In order to
+get that to work, ACPI assumes each device has defined D-states and that these
+can be controlled through the optional ACPI methods _PS0, _PS1, _PS2, and _PS3;
+in ACPI, _PS0 is the method to invoke to turn a device full on, and _PS3 is for
+turning a device full off.
+
+There are two options for using those Power Resources.  They can:
+
+   -- be managed in a _PSx method which gets called on entry to power
+      state Dx.
+
+   -- be declared separately as power resources with their own _ON and _OFF
+      methods.  They are then tied back to D-states for a particular device
+      via _PRx which specifies which power resources a device needs to be on
+      while in Dx.  Kernel then tracks number of devices using a power resource
+      and calls _ON/_OFF as needed.
+
+The kernel ACPI code will also assume that the _PSx methods follow the normal
+ACPI rules for such methods:
+
+   -- If either _PS0 or _PS3 is implemented, then the other method must also
+      be implemented.
+
+   -- If a device requires usage or setup of a power resource when on, the ASL
+      should organize that it is allocated/enabled using the _PS0 method.
+
+   -- Resources allocated or enabled in the _PS0 method should be disabled
+      or de-allocated in the _PS3 method.
+
+   -- Firmware will leave the resources in a reasonable state before handing
+      over control to the kernel.
+
+Such code in _PSx methods will of course be very platform specific.  But,
+this allows the driver to abstract out the interface for operating the device
+and avoid having to read special non-standard values from ACPI tables. Further,
+abstracting the use of these resources allows the hardware to change over time
+without requiring updates to the driver.
+
+
+Clocks
+------
+ACPI makes the assumption that clocks are initialized by the firmware --
+UEFI, in this case -- to some working value before control is handed over
+to the kernel.  This has implications for devices such as UARTs, or SoC-driven
+LCD displays, for example.
+
+When the kernel boots, the clocks are assumed to be set to reasonable
+working values.  If for some reason the frequency needs to change -- e.g.,
+throttling for power management -- the device driver should expect that
+process to be abstracted out into some ACPI method that can be invoked
+(please see the ACPI specification for further recommendations on standard
+methods to be expected).  The only exceptions to this are CPU clocks where
+CPPC provides a much richer interface than ACPI methods.  If the clocks
+are not set, there is no direct way for Linux to control them.
+
+If an SoC vendor wants to provide fine-grained control of the system clocks,
+they could do so by providing ACPI methods that could be invoked by Linux
+drivers.  However, this is NOT recommended and Linux drivers should NOT use
+such methods, even if they are provided.  Such methods are not currently
+standardized in the ACPI specification, and using them could tie a kernel
+to a very specific SoC, or tie an SoC to a very specific version of the
+kernel, both of which we are trying to avoid.
+
+
+Driver Recommendations
+----------------------
+DO NOT remove any DT handling when adding ACPI support for a driver.  The
+same device may be used on many different systems.
+
+DO try to structure the driver so that it is data-driven.  That is, set up
+a struct containing internal per-device state based on defaults and whatever
+else must be discovered by the driver probe function.  Then, have the rest
+of the driver operate off of the contents of that struct.  Doing so should
+allow most divergence between ACPI and DT functionality to be kept local to
+the probe function instead of being scattered throughout the driver.  For
+example:
+
+static int device_probe_dt(struct platform_device *pdev)
+{
+       /* DT specific functionality */
+       ...
+}
+
+static int device_probe_acpi(struct platform_device *pdev)
+{
+       /* ACPI specific functionality */
+       ...
+}
+
+static int device_probe(struct platform_device *pdev)
+{
+       ...
+       struct device_node node = pdev->dev.of_node;
+       ...
+
+       if (node)
+               ret = device_probe_dt(pdev);
+       else if (ACPI_HANDLE(&pdev->dev))
+               ret = device_probe_acpi(pdev);
+       else
+               /* other initialization */
+               ...
+       /* Continue with any generic probe operations */
+       ...
+}
+
+DO keep the MODULE_DEVICE_TABLE entries together in the driver to make it
+clear the different names the driver is probed for, both from DT and from
+ACPI:
+
+static struct of_device_id virtio_mmio_match[] = {
+        { .compatible = "virtio,mmio", },
+        { }
+};
+MODULE_DEVICE_TABLE(of, virtio_mmio_match);
+
+static const struct acpi_device_id virtio_mmio_acpi_match[] = {
+        { "LNRO0005", },
+        { }
+};
+MODULE_DEVICE_TABLE(acpi, virtio_mmio_acpi_match);
+
+
+ASWG
+----
+The ACPI specification changes regularly.  During the year 2014, for instance,
+version 5.1 was released and version 6.0 substantially completed, with most of
+the changes being driven by ARM-specific requirements.  Proposed changes are
+presented and discussed in the ASWG (ACPI Specification Working Group) which
+is a part of the UEFI Forum.
+
+Participation in this group is open to all UEFI members.  Please see
+http://www.uefi.org/workinggroup for details on group membership.
+
+It is the intent of the ARMv8 ACPI kernel code to follow the ACPI specification
+as closely as possible, and to only implement functionality that complies with
+the released standards from UEFI ASWG.  As a practical matter, there will be
+vendors that provide bad ACPI tables or violate the standards in some way.
+If this is because of errors, quirks and fixups may be necessary, but will
+be avoided if possible.  If there are features missing from ACPI that preclude
+it from being used on a platform, ECRs (Engineering Change Requests) should be
+submitted to ASWG and go through the normal approval process; for those that
+are not UEFI members, many other members of the Linux community are and would
+likely be willing to assist in submitting ECRs.
+
+
+Linux Code
+----------
+Individual items specific to Linux on ARM, contained in the the Linux
+source code, are in the list that follows:
+
+ACPI_OS_NAME           This macro defines the string to be returned when
+                       an ACPI method invokes the _OS method.  On ARM64
+                       systems, this macro will be "Linux" by default.
+                       The command line parameter acpi_os=<string>
+                       can be used to set it to some other value.  The
+                       default value for other architectures is "Microsoft
+                       Windows NT", for example.

+QCOM Idle States for cpuidle driver
+
+ARM provides idle-state node to define the cpuidle states, as defined in [1].
+cpuidle-qcom is the cpuidle driver for Qualcomm SoCs and uses these idle
+states. Idle states have different enter/exit latency and residency values.
+The idle states supported by the QCOM SoC are defined as -
+
+    * Standby
+    * Retention
+    * Standalone Power Collapse (Standalone PC or SPC)
+    * Power Collapse (PC)
+
+Standby: Standby does a little more in addition to architectural clock gating.
+When the WFI instruction is executed the ARM core would gate its internal
+clocks. In addition to gating the clocks, QCOM cpus use this instruction as a
+trigger to execute the SPM state machine. The SPM state machine waits for the
+interrupt to trigger the core back in to active. This triggers the cache
+hierarchy to enter standby states, when all cpus are idle. An interrupt brings
+the SPM state machine out of its wait, the next step is to ensure that the
+cache hierarchy is also out of standby, and then the cpu is allowed to resume
+execution. This state is defined as a generic ARM WFI state by the ARM cpuidle
+driver and is not defined in the DT. The SPM state machine should be
+configured to execute this state by default and after executing every other
+state below.
+
+Retention: Retention is a low power state where the core is clock gated and
+the memory and the registers associated with the core are retained. The
+voltage may be reduced to the minimum value needed to keep the processor
+registers active. The SPM should be configured to execute the retention
+sequence and would wait for interrupt, before restoring the cpu to execution
+state. Retention may have a slightly higher latency than Standby.
+
+Standalone PC: A cpu can power down and warmboot if there is a sufficient time
+between the time it enters idle and the next known wake up. SPC mode is used
+to indicate a core entering a power down state without consulting any other
+cpu or the system resources. This helps save power only on that core.  The SPM
+sequence for this idle state is programmed to power down the supply to the
+core, wait for the interrupt, restore power to the core, and ensure the
+system state including cache hierarchy is ready before allowing core to
+resume. Applying power and resetting the core causes the core to warmboot
+back into Elevation Level (EL) which trampolines the control back to the
+kernel. Entering a power down state for the cpu, needs to be done by trapping
+into a EL. Failing to do so, would result in a crash enforced by the warm boot
+code in the EL for the SoC. On SoCs with write-back L1 cache, the cache has to
+be flushed in s/w, before powering down the core.
+
+Power Collapse: This state is similar to the SPC mode, but distinguishes
+itself in that the cpu acknowledges and permits the SoC to enter deeper sleep
+modes. In a hierarchical power domain SoC, this means L2 and other caches can
+be flushed, system bus, clocks - lowered, and SoC main XO clock gated and
+voltages reduced, provided all cpus enter this state.  Since the span of low
+power modes possible at this state is vast, the exit latency and the residency
+of this low power mode would be considered high even though at a cpu level,
+this essentially is cpu power down. The SPM in this state also may handshake
+with the Resource power manager (RPM) processor in the SoC to indicate a
+complete application processor subsystem shut down.
+
+The idle-state for QCOM SoCs are distinguished by the compatible property of
+the idle-states device node.
+
+The devicetree representation of the idle state should be -

+OMAP Control Module bindings
+
+Control Module contains miscellaneous features under it based on SoC type.
+Pincontrol is one common feature, and it has a specialized support
+described in [1]. Typically some clock nodes are also under control module.
+Syscon is used to share register level access to drivers external to
+control module driver itself.
+
+See [2] for documentation about clock/clockdomain nodes.

+Renesas Bus State Controller (BSC)
+==================================
+
+The Renesas Bus State Controller (BSC, sometimes called "LBSC within Bus
+Bridge", or "External Bus Interface") can be found in several Renesas ARM SoCs.
+It provides an external bus for connecting multiple external devices to the
+SoC, driving several chip select lines, for e.g. NOR FLASH, Ethernet and USB.
+
+While the BSC is a fairly simple memory-mapped bus, it may be part of a PM
+domain, and may have a gateable functional clock.
+Before a device connected to the BSC can be accessed, the PM domain
+containing the BSC must be powered on, and the functional clock
+driving the BSC must be enabled.
+
+The bindings for the BSC extend the bindings for "simple-pm-bus".
+
+
+Required properties
+  - compatible: Must contain an SoC-specific value, and "renesas,bsc" and
+		"simple-pm-bus" as fallbacks.
+                SoC-specific values can be:
+		"renesas,bsc-r8a73a4" for R-Mobile APE6 (r8a73a4)
+		"renesas,bsc-sh73a0" for SH-Mobile AG5 (sh73a0)
+  - #address-cells, #size-cells, ranges: Must describe the mapping between
+		parent address and child address spaces.
+  - reg: Must contain the base address and length to access the bus controller.
+
+Optional properties:
+  - interrupts: Must contain a reference to the BSC interrupt, if available.
+  - clocks: Must contain a reference to the functional clock, if available.
+  - power-domains: Must contain a reference to the PM domain, if available.
+
+
+Example:
+
+	bsc: bus@fec10000 {
+		compatible = "renesas,bsc-sh73a0", "renesas,bsc",
+			     "simple-pm-bus";
+		#address-cells = <1>;

+Simple Power-Managed Bus
+========================
+
+A Simple Power-Managed Bus is a transparent bus that doesn't need a real
+driver, as it's typically initialized by the boot loader.
+
+However, its bus controller is part of a PM domain, or under the control of a
+functional clock.  Hence, the bus controller's PM domain and/or clock must be
+enabled for child devices connected to the bus (either on-SoC or externally)
+to function.
+
+While "simple-pm-bus" follows the "simple-bus" set of properties, as specified
+in ePAPR, it is not an extension of "simple-bus".
+
+
+Required properties:
+  - compatible: Must contain at least "simple-pm-bus".
+		Must not contain "simple-bus".
+		It's recommended to let this be preceded by one or more
+		vendor-specific compatible values.
+  - #address-cells, #size-cells, ranges: Must describe the mapping between
+		parent address and child address spaces.
+
+Optional platform-specific properties for clock or PM domain control (at least
+one of them is required):
+  - clocks: Must contain a reference to the functional clock(s),
+  - power-domains: Must contain a reference to the PM domain.
+Please refer to the binding documentation for the clock and/or PM domain
+providers for more details.
+

+Example:

+Common properties
+
+The ePAPR specification does not define any properties related to hardware
+byteswapping, but endianness issues show up frequently in porting Linux to
+different machine types.  This document attempts to provide a consistent
+way of handling byteswapping across drivers.
+
+Optional properties:
+ - big-endian: Boolean; force big endian register accesses
+   unconditionally (e.g. ioread32be/iowrite32be).  Use this if you
+   know the peripheral always needs to be accessed in BE mode.
+ - little-endian: Boolean; force little endian register accesses
+   unconditionally (e.g. readl/writel).  Use this if you know the
+   peripheral always needs to be accessed in LE mode.
+ - native-endian: Boolean; always use register accesses matched to the
+   endianness of the kernel binary (e.g. LE vmlinux -> readl/writel,
+   BE vmlinux -> ioread32be/iowrite32be).  In this case no byteswaps
+   will ever be performed.  Use this if the hardware "self-adjusts"
+   register endianness based on the CPU's configured endianness.
+
+If a binding supports these properties, then the binding should also
+specify the default behavior if none of these properties are present.
+In such cases, little-endian is the preferred default, but it is not
+a requirement.  The of_device_is_big_endian() and of_fdt_is_big_endian()
+helper functions do assume that little-endian is the default, because
+most existing (PCI-based) drivers implicitly default to LE by using
+readl/writel for MMIO accesses.
+
+Examples:
+Scenario 1 : CPU in LE mode & device in LE mode.
+dev: dev@40031000 {
+	      compatible = "name";
+	      reg = <0x40031000 0x1000>;
+	      ...
+	      native-endian;
+};
+
+Scenario 2 : CPU in LE mode & device in BE mode.
+dev: dev@40031000 {
+	      compatible = "name";
+	      reg = <0x40031000 0x1000>;
+	      ...
+	      big-endian;
+};
+
+Scenario 3 : CPU in BE mode & device in BE mode.
+dev: dev@40031000 {
+	      compatible = "name";
+	      reg = <0x40031000 0x1000>;
+	      ...
+	      native-endian;
+};

+	      compatible = "name";
+	      reg = <0x40031000 0x1000>;

+- compatible: Should be "apm,xgene-dma".
+- device_type: set to "dma".
+- reg: Address and length of the register set for the device.

+* Ingenic JZ4780 DMA Controller
+
+Required properties:

+- compatible: Should be "ingenic,jz4780-dma"
+- reg: Should contain the DMA controller registers location and length.
+- interrupts: Should contain the interrupt specifier of the DMA controller.
+- interrupt-parent: Should be the phandle of the interrupt controller that
+- clocks: Should contain a clock specifier for the JZ4780 PDMA clock.
+- #dma-cells: Must be <2>. Number of integer cells in the dmas property of
+  DMA clients (see below).
+
+Optional properties:
+
+- ingenic,reserved-channels: Bitmask of channels to reserve for devices that
+  need a specific channel. These channels will only be assigned when explicitly
+  requested by a client. The primary use for this is channels 0 and 1, which
+  can be configured to have special behaviour for NAND/BCH when using
+  programmable firmware.
+
+Example:
+
+dma: dma@13420000 {
+	compatible = "ingenic,jz4780-dma";
+	reg = <0x13420000 0x10000>;

+
+	#dma-cells = <2>;
+
+	ingenic,reserved-channels = <0x3>;
+};
+
+DMA clients must use the format described in dma.txt, giving a phandle to the
+DMA controller plus the following 2 integer cells:
+
+1. Request type: The DMA request type for transfers to/from the device on
+   the allocated channel, as defined in the SoC documentation.
+
+2. Channel: If set to 0xffffffff, any available channel will be allocated for
+   the client. Otherwise, the exact channel specified will be used. The channel
+   should be reserved on the DMA controller using the ingenic,reserved-channels
+   property.
+
+Example:
+
+uart0: serial@10030000 {
+	...
+	dmas = <&dma 0x14 0xffffffff

+DT bindings for Xilinx video IP cores
+-------------------------------------
+
+Xilinx video IP cores process video streams by acting as video sinks and/or
+sources. They are connected by links through their input and output ports,
+creating a video pipeline.
+
+Each video IP core is represented by an AMBA bus child node in the device
+tree using bindings documented in this directory. Connections between the IP
+cores are represented as defined in ../video-interfaces.txt.
+
+The whole  pipeline is represented by an AMBA bus child node in the device
+tree using bindings documented in ./xlnx,video.txt.
+
+Common properties
+-----------------
+
+The following properties are common to all Xilinx video IP cores.
+
+- xlnx,video-format: This property represents a video format transmitted on an
+  AXI bus between video IP cores, using its VF code as defined in "AXI4-Stream
+  Video IP and System Design Guide" [UG934]. How the format relates to the IP
+  core is decribed in the IP core bindings documentation.
+
+- xlnx,video-width: This property qualifies the video format with the sample
+  width expressed as a number of bits per pixel component. All components must
+  use the same width.
+
+- xlnx,cfa-pattern: When the video format is set to Mono/Sensor, this property
+  describes the sensor's color filter array pattern. Supported values are
+  "bggr", "gbrg", "grbg", "rggb" and "mono". If not specified, the pattern
+  defaults to "mono".

+node of the VIPP represents as a top level node of the pipeline and defines
+mappings between DMAs and the video IP cores.
+
+Required properties:
+
+- compatible: Must be "xlnx,video".
+
+- dmas, dma-names: List of one DMA specifier and identifier string (as defined
+  in Documentation/devicetree/bindings/dma/dma.txt) per port. Each port
+  requires a DMA channel with the identifier string set to "port" followed by
+  the port index.
+
+- ports: Video port, using the DT bindings defined in ../video-interfaces.txt.
+
+Required port properties:
+
+- direction: should be either "input" or "output" depending on the direction
+  of stream.
+
+Example:
+
+	video_cap {
+		compatible = "xlnx,video";
+		dmas = <&vdma_1 1>, <&vdma_3 1>;

+This file documents the device tree bindings for the NEMC external memory
+controller in Ingenic JZ4780
+
+Required properties:
+- compatible: Should be set to one of:
+    "ingenic,jz4780-nemc" (JZ4780)
+- reg: Should specify the NEMC controller registers location and length.
+- clocks: Clock for the NEMC controller.
+- #address-cells: Must be set to 2.
+- #size-cells: Must be set to 1.
+- ranges: A set of ranges for each bank describing the physical memory layout.
+  Each should specify the following 4 integer values:
+
+    <cs number> 0 <physical address of mapping> <size of mapping>
+
+Each child of the NEMC node describes a device connected to the NEMC.
+
+Required child node properties:
+- reg: Should contain at least one register specifier, given in the following
+  format:
+
+    <cs number> <offset> <size>
+
+  Multiple registers can be specified across multiple banks. This is needed,
+  for example, for packaged NAND devices with multiple dies. Such devices
+  should be grouped into a single node.
+
+Optional child node properties:
+- ingenic,nemc-bus-width: Specifies the bus width in bits. Defaults to 8 bits.
+- ingenic,nemc-tAS: Address setup time in nanoseconds.
+- ingenic,nemc-tAH: Address hold time in nanoseconds.
+- ingenic,nemc-tBP: Burst pitch time in nanoseconds.
+- ingenic,nemc-tAW: Access wait time in nanoseconds.
+- ingenic,nemc-tSTRV: Static memory recovery time in nanoseconds.
+
+If a child node references multiple banks in its "reg" property, the same value
+for all optional parameters will be configured for all banks. If any optional
+parameters are omitted, they will be left unchanged from whatever they are
+configured to when the NEMC device is probed (which may be the reset value as
+given in the hardware reference manual, or a value configured by the boot
+loader).

+Specifying power domain for IP modules
+======================================
+
+IP cores belonging to a power domain should contain a 'power-domains' property
+that is a phandle pointing to the gpc device node and a DOMAIN_INDEX specifying
+the power domain the device belongs to.
+
+Example of a device that is part of the PU power domain:
+
+	vpu: vpu@02040000 {
+		reg = <0x02040000 0x3c000>;
+		/* ... */
+		power-domains = <&gpc 1>;
+		/* ... */
+	};
+
+The following DOMAIN_INDEX values are valid for i.MX6Q:
+ARM_DOMAIN     0
+PU_DOMAIN      1
+The following additional DOMAIN_INDEX value is valid for i.MX6SL:
+DISPLAY_DOMAIN 2

+MediaTek PMIC Wrapper Driver
+
+This document describes the binding for the MediaTek PMIC wrapper.
+
+On MediaTek SoCs the PMIC is connected via SPI. The SPI master interface
+is not directly visible to the CPU, but only through the PMIC wrapper
+inside the SoC. The communication between the SoC and the PMIC can
+optionally be encrypted. Also a non standard Dual IO SPI mode can be
+used to increase speed.
+
+IP Pairing
+
+on MT8135 the pins of some SoC internal peripherals can be on the PMIC.
+The signals of these pins are routed over the SPI bus using the pwrap
+bridge. In the binding description below the properties needed for bridging
+are marked with "IP Pairing". These are optional on SoCs which do not support
+IP Pairing
+
+Required properties in pwrap device node.
+- compatible:
+	"mediatek,mt8135-pwrap" for MT8135 SoCs
+	"mediatek,mt8173-pwrap" for MT8173 SoCs
+- interrupts: IRQ for pwrap in SOC
+- reg-names: Must include the following entries:
+  "pwrap": Main registers base
+  "pwrap-bridge": bridge base (IP Pairing)
+- reg: Must contain an entry for each entry in reg-names.
+- reset-names: Must include the following entries:
+  "pwrap"
+  "pwrap-bridge" (IP Pairing)
+- resets: Must contain an entry for each entry in reset-names.
+- clock-names: Must include the following entries:
+  "spi": SPI bus clock
+  "wrap": Main module clock
+- clocks: Must contain an entry for each entry in clock-names.
+
+Optional properities:
+- pmic: Mediatek PMIC MFD is the child device of pwrap
+  See the following for child node definitions:
+  Documentation/devicetree/bindings/mfd/mt6397.txt

+The cluster MD is a shared-device RAID for a cluster.
+
+
+1. On-disk format
+
+Separate write-intent-bitmap are used for each cluster node.
+The bitmaps record all writes that may have been started on that node,
+and may not yet have finished. The on-disk layout is:
+
+0                    4k                     8k                    12k
+-------------------------------------------------------------------
+| idle                | md super            | bm super [0] + bits |
+| bm bits[0, contd]   | bm super[1] + bits  | bm bits[1, contd]   |
+| bm super[2] + bits  | bm bits [2, contd]  | bm super[3] + bits  |
+| bm bits [3, contd]  |                     |                     |
+
+During "normal" functioning we assume the filesystem ensures that only one
+node writes to any given block at a time, so a write
+request will
+ - set the appropriate bit (if not already set)
+ - commit the write to all mirrors
+ - schedule the bit to be cleared after a timeout.
+
+Reads are just handled normally.  It is up to the filesystem to
+ensure one node doesn't read from a location where another node (or the same
+node) is writing.
+
+
+2. DLM Locks for management
+
+There are two locks for managing the device:
+
+2.1 Bitmap lock resource (bm_lockres)
+
+ The bm_lockres protects individual node bitmaps. They are named in the
+ form bitmap001 for node 1, bitmap002 for node and so on. When a node
+ joins the cluster, it acquires the lock in PW mode and it stays so
+ during the lifetime the node is part of the cluster. The lock resource
+ number is based on the slot number returned by the DLM subsystem. Since
+ DLM starts node count from one and bitmap slots start from zero, one is
+ subtracted from the DLM slot number to arrive at the bitmap slot number.
+
+3. Communication
+
+Each node has to communicate with other nodes when starting or ending
+resync, and metadata superblock updates.
+
+3.1 Message Types
+
+ There are 3 types, of messages which are passed
+
+ 3.1.1 METADATA_UPDATED: informs other nodes that the metadata has been
+   updated, and the node must re-read the md superblock. This is performed
+   synchronously.
+
+ 3.1.2 RESYNC: informs other nodes that a resync is initiated or ended
+   so that each node may suspend or resume the region.
+
+3.2 Communication mechanism
+
+ The DLM LVB is used to communicate within nodes of the cluster. There
+ are three resources used for the purpose:
+
+  3.2.1 Token: The resource which protects the entire communication
+   system. The node having the token resource is allowed to
+   communicate.
+
+  3.2.2 Message: The lock resource which carries the data to
+   communicate.
+
+  3.2.3 Ack: The resource, acquiring which means the message has been
+   acknowledged by all nodes in the cluster. The BAST of the resource
+   is used to inform the receive node that a node wants to communicate.
+
+The algorithm is:
+
+ 1. receive status
+
+   sender                         receiver                   receiver
+   ACK:CR                          ACK:CR                     ACK:CR
+
+ 2. sender get EX of TOKEN
+    sender get EX of MESSAGE
+    sender                        receiver                 receiver
+    TOKEN:EX                       ACK:CR                   ACK:CR
+    MESSAGE:EX
+    ACK:CR
+
+    Sender checks that it still needs to send a message. Messages received
+    or other events that happened while waiting for the TOKEN may have made
+    this message inappropriate or redundant.
+
+ 3. sender write LVB.
+    sender down-convert MESSAGE from EX to CR
+    sender try to get EX of ACK
+    [ wait until all receiver has *processed* the MESSAGE ]
+
+                                     [ triggered by bast of ACK ]
+                                     receiver get CR of MESSAGE
+                                     receiver read LVB
+                                     receiver processes the message
+                                     [ wait finish ]
+                                     receiver release ACK
+
+   sender                         receiver                   receiver
+   TOKEN:EX                       MESSAGE:CR                 MESSAGE:CR
+   MESSAGE:CR
+   ACK:EX
+
+ 4. triggered by grant of EX on ACK (indicating all receivers have processed
+    message)
+    sender down-convert ACK from EX to CR
+    sender release MESSAGE
+    sender release TOKEN
+                               receiver upconvert to EX of MESSAGE
+                               receiver get CR of ACK
+                               receiver release MESSAGE
+
+   sender                      receiver                   receiver
+   ACK:CR                       ACK:CR                     ACK:CR
+
+
+4. Handling Failures
+
+4.1 Node Failure
+ When a node fails, the DLM informs the cluster with the slot. The node
+ starts a cluster recovery thread. The cluster recovery thread:
+	- acquires the bitmap<number> lock of the failed node
+	- opens the bitmap
+	- reads the bitmap of the failed node
+	- copies the set bitmap to local node
+	- cleans the bitmap of the failed node
+	- releases bitmap<number> lock of the failed node
+	- initiates resync of the bitmap on the current node
+
+ The resync process, is the regular md resync. However, in a clustered
+ environment when a resync is performed, it needs to tell other nodes
+ of the areas which are suspended. Before a resync starts, the node
+ send out RESYNC_START with the (lo,hi) range of the area which needs
+ to be suspended. Each node maintains a suspend_list, which contains
+ the list  of ranges which are currently suspended. On receiving
+ RESYNC_START, the node adds the range to the suspend_list. Similarly,
+ when the node performing resync finishes, it send RESYNC_FINISHED
+ to other nodes and other nodes remove the corresponding entry from
+ the suspend_list.
+
+ A helper function, should_suspend() can be used to check if a particular
+ I/O range should be suspended or not.
+
+4.2 Device Failure
+ Device failures are handled and communicated with the metadata update
+ routine.
+
+5. Adding a new Device
+For adding a new device, it is necessary that all nodes "see" the new device
+to be added. For this, the following algorithm is used:
+
+    1. Node 1 issues mdadm --manage /dev/mdX --add /dev/sdYY which issues
+       ioctl(ADD_NEW_DISC with disc.state set to MD_DISK_CLUSTER_ADD)
+    2. Node 1 sends NEWDISK with uuid and slot number
+    3. Other nodes issue kobject_uevent_env with uuid and slot number
+       (Steps 4,5 could be a udev rule)
+    4. In userspace, the node searches for the disk, perhaps
+       using blkid -t SUB_UUID=""
+    5. Other nodes issue either of the following depending on whether the disk
+       was found:
+       ioctl(ADD_NEW_DISK with disc.state set to MD_DISK_CANDIDATE and
+                disc.number set to slot number)
+       ioctl(CLUSTERED_DISK_NACK)
+    6. Other nodes drop lock on no-new-devs (CR) if device is found
+    7. Node 1 attempts EX lock on no-new-devs
+    8. If node 1 gets the lock, it sends METADATA_UPDATED after unmarking the disk
+       as SpareLocal
+    9. If not (get no-new-dev lock), it fails the operation and sends METADATA_UPDATED
+    10. Other nodes get the information whether a disk is added or not
+	by the following METADATA_UPDATED.

+ *
+ * cluster_powerup:

+ * disabled. Called before first cpu_powerup when cluster is down. Must
+ * return 0 for success or negative error code.
+ *
+ * cpu_suspend_prepare:
+ * Special suspend configuration. Called on target CPU with MCPM lock held

+ *
+ * cpu_powerdown_prepare:
+ * Configure given CPU for power down. Called on target CPU with MCPM lock

+ *
+ * cluster_powerdown_prepare:
+ * Configure given cluster for power down. Called on one CPU from target

+ * for each CPU in the cluster has happened when this occurs.
+ *
+ * cpu_cache_disable:
+ * Clean and disable CPU level cache for the calling CPU. Called on with IRQs

+ *
+ * cluster_cache_disable:
+ * Clean and disable the cluster wide cache as well as the CPU level cache
+ * for the calling CPU. No call to cpu_cache_disable will happen for this

+ *
+ * cpu_is_up:
+ * Called on given CPU after it has been powered up or resumed. The MCPM lock

+ * R-Car Generation 2 da9063/da9210 regulator quirk
+ *
+ * The r8a7790/lager and r8a7791/koelsch development boards have da9063 and
+ * da9210 regulators.  Both regulators have their interrupt request lines tied
+ * to the same interrupt pin (IRQ2) on the SoC.
+ *
+ * After cold boot or da9063-induced restart, both the da9063 and da9210 seem
+ * to assert their interrupt request lines.  Hence as soon as one driver
+ * requests this irq, it gets stuck in an interrupt storm, as it only manages
+ * to deassert its own interrupt request line, and the other driver hasn't
+ * installed an interrupt handler yet.
+ *
+ * To handle this, install a quirk that masks the interrupts in both the
+ * da9063 and da9210.  This quirk has to run after the i2c master driver has
+ * been initialized, but before the i2c slave drivers are initialized.

+ *
+ * General capabilities:
+ *	RAID Engine (RE) block is capable of offloading XOR, memcpy and P/Q
+ *	calculations required in RAID5 and RAID6 operations. RE driver
+ *	registers with Linux's ASYNC layer as dma driver. RE hardware
+ *	maintains strict ordering of the requests through chained
+ *	command queueing.
+ *
+ * Data flow:
+ *	Software RAID layer of Linux (MD layer) maintains RAID partitions,
+ *	strips, stripes etc. It sends requests to the underlying ASYNC layer
+ *	which further passes it to RE driver. ASYNC layer decides which request
+ *	goes to which job ring of RE hardware. For every request processed by
+ *	RAID Engine, driver gets an interrupt unless coalescing is set. The
+ *	per job ring interrupt handler checks the status register for errors,
+ *	clears the interrupt and leave the post interrupt processing to the irq
+ *	thread.

+	help
+	  This framework provides a kernel interface for the CoreSight debug
+	  and trace drivers to register themselves with. It's intended to build

+	  specification and configure the right serie of components when a
+	  trace source gets enabled.

+config CORESIGHT_LINKS_AND_SINKS
+	bool "CoreSight Link and Sink drivers"
+	help
+	  This enables support for CoreSight link and sink drivers that are
+	  responsible for transporting and collecting the trace data
+	  respectively.  Link and sinks are dynamically aggregated with a trace
+	  entity at run time to form a complete trace path.
+
+config CORESIGHT_LINK_AND_SINK_TMC
+	bool "Coresight generic TMC driver"
+	depends on CORESIGHT_LINKS_AND_SINKS
+	help
+	  This enables support for the Trace Memory Controller driver.
+	  Depending on its configuration the device can act as a link (embedded
+	  trace router - ETR) or sink (embedded trace FIFO).  The driver
+	  complies with the generic implementation of the component without
+	  special enhancement or added features.
+
+config CORESIGHT_SINK_TPIU
+	bool "Coresight generic TPIU driver"
+	depends on CORESIGHT_LINKS_AND_SINKS
+	help
+	  This enables support for the Trace Port Interface Unit driver,

+	  components and a trace for bridging the gap between the on-chip
+	  coresight components and a trace port collection engine, typically
+	  connected to an external host for use case capturing more traces than
+	  the on-board coresight memory can handle.

+	bool "CoreSight Embedded Trace Macrocell 3.x driver"

+	  This driver provides support for processor ETM3.x and PTM1.x modules,
+	  which allows tracing the instructions that a processor is executing
+	  This is primarily useful for instruction level tracing.  Depending
+	  the ETM version data tracing may also be available.

+ * sb_start_intwrite() in btrfs_start_transaction().
+ * Not locking i_mutex of the inodes is still safe because:
+ *
+ * 1) For regular files we log with a mode of LOG_INODE_EXISTS. It's possible
+ *    that while logging the inode new references (names) are added or removed
+ *    from the inode, leaving the logged inode item with a link count that does
+ *    not match the number of logged inode reference items. This is fine because
+ *    at log replay time we compute the real number of links and correct the
+ *    link count in the inode item (see replay_one_buffer() and
+ *    link_to_fixup_dir());
+ *
+ * 2) For directories we log with a mode of LOG_INODE_ALL. It's possible that
+ *    while logging the inode's items new items with keys BTRFS_DIR_ITEM_KEY and
+ *    BTRFS_DIR_INDEX_KEY are added to fs/subvol tree and the logged inode item
+ *    has a size that doesn't match the sum of the lengths of all the logged
+ *    names. This does not result in a problem because if a dir_item key is
+ *    logged but its matching dir_index key is not logged, at log replay time we
+ *    don't use it to replay the respective name (see replay_one_name()). On the
+ *    other hand if only the dir_index key ends up being logged, the respective
+ *    name is added to the fs/subvol tree with both the dir_item and dir_index
+ *    keys created (see replay_one_name()).
+ *    The directory's inode item with a wrong i_size is not a problem as well,

- * Per-cpu incore superblock counters
- *
- * Simple concept, difficult implementation
- *
- * Basically, replace the incore superblock counters with a distributed per cpu
- * counter for contended fields (e.g.  free block count).
- *
- * Difficulties arise in that the incore sb is used for ENOSPC checking, and
- * hence needs to be accurately read when we are running low on space. Hence
- * there is a method to enable and disable the per-cpu counters based on how
- * much "stuff" is available in them.
- *
- * Basically, a counter is enabled if there is enough free resource to justify
- * running a per-cpu fast-path. If the per-cpu counter runs out (i.e. a local
- * ENOSPC), then we disable the counters to synchronise all callers and
- * re-distribute the available resources.
- *
- * If, once we redistributed the available resources, we still get a failure,
- * we disable the per-cpu counter and go through the slow path.
- *
- * The slow path is the current xfs_mod_incore_sb() function.  This means that
- * when we disable a per-cpu counter, we need to drain its resources back to
- * the global superblock. We do this after disabling the counter to prevent
- * more threads from queueing up on the counter.
- *
- * Essentially, this means that we still need a lock in the fast path to enable
- * synchronisation between the global counters and the per-cpu counters. This
- * is not a problem because the lock will be local to a CPU almost all the time
- * and have little contention except when we get to ENOSPC conditions.
- *
- * Basically, this lock becomes a barrier that enables us to lock out the fast
- * path while we do things like enabling and disabling counters and
- * synchronising the counters.
- *
- * Locking rules:
- *
- * 	1. m_sb_lock before picking up per-cpu locks
- * 	2. per-cpu locks always picked up via for_each_online_cpu() order
- * 	3. accurate counter sync requires m_sb_lock + per cpu locks
- * 	4. modifying per-cpu counters requires holding per-cpu lock
- * 	5. modifying global counters requires holding m_sb_lock
- *	6. enabling or disabling a counter requires holding the m_sb_lock 
- *	   and _none_ of the per-cpu locks.
- *
- * Disabled counters are only ever re-enabled by a balance operation
- * that results in more free resources per CPU than a given threshold.
- * To ensure counters don't remain disabled, they are rebalanced when
- * the global resource goes above a higher threshold (i.e. some hysteresis
- * is present to prevent thrashing).
