Add a driver for the keyboard, touchpad and USB port of
the keyboard dock for the Asus TF103C 2-in-1 tablet.
This keyboard dock has its own I2C attached embedded controller
and the keyboard and touchpad are also connected over I2C,
instead of using the usual USB connection. This means that the
keyboard dock requires this special driver to function.

The whitelabel (sold as various brands) TM800A550L tablets's DSDT contains
a whole bunch of bogus ACPI I2C devices and the ACPI node describing
the touchscreen is bad (the IRQ is missing). Enumeration of these is
skipped through the acpi_quirk_skip_i2c_client_enumeration().
Add support for manually instantiating the (now) missing I2C devices by
adding the necessary device info to the x86-android-tablets module,
including instantiating an actually working i2c-client for
the touchscreen.

Since the x86-android-tablets code does all it work from module_init() it
cannot use -EPROBE_DEFER to wait for e.g. interrupt providing GPIO-chips
or PMIC-cells to show up.
To make sure things will still work when some necessary resource providers
are build as module allow the per board info to specify a list of modules
to pre-load before instantiating the I2C clients.

identical.
Specifically for the pdevs flow pdev_count must only be set after

x86_android_tablet_cleanup() and the i2c_clients flow is updated

The Crystal Cove PMIC has a pin which can be used to connect the IRQ of
an external charger IC. On some boards this is used so we need a way to
look this up.
Note that the Intel PMICs have 2 levels of interrupts and thus
2 levels of IRQ domains all tied to a single fwnode.
Level 1 is the irqchip which demultiplexes the actual PMIC interrupt into
interrupts for the various MFD cells. Level 2 are the irqchips used in the
cell drivers which themselves export IRQs, such as the crystal_cove_gpio
driver, which de-multiplexes the level 2 interrupts for the GPIOs into
individual per GPIO IRQs.
The crystal_cove_charger driver registers an irqchip with a single IRQ for
the charger driver to consume. Note the MFD cell IRQ cannot be consumed
directly because the level 2 interrupts must be explicitly acked.
To allow finding the right IRQ domain when looking up the IRQ for
the charger, the crystal_cove_charger driver sets a DOMAIN_BUS_WIRED token
on its IRQ domain.
Add support for looking up the IRQ from the crystal_cove_charger driver.

The Glavey TM800A550L tablet is a tablet which ships with Android as
factory OS. As such it has the typical broken DSDT which x86 Android
tablets tend to have.
Specifically the touchscreen ACPI device node is missing the IRQ for
the touchscreen. So far users were expected to fix this with a DSDT
overlay, but support for the TM800A550L has been added to the new
x86-android-modules kernel-module and that will now automatically
instantiate a proper i2c-client with the IRQ set for the touchscreen,
including the necessary device-properties for the firmware loading.
This means that the touchscreen_dmi entry for the TM800A550L is
no longer necessary (and it no longer matches either since the
touchscreen is no longer enumerated through ACPI), remove it.

The firmware distributed as part of the Windows and Android drivers uses
significantly different min and max values for the x- and y-axis,
compared to the EFI's embedded touchscreen firmware.
The difference is large enough that e.g. typing on an onscreen keyboard
results in the wrong "keys" getting pressed.
Adjust the values to match those of the firmware distributed with the
Windows and Android drivers (which is necessary for pen support) and
put the EFI-fw version's min/max values in the new "silead,efi-fw-min-max"
property. The silead driver will use these when it is using the
EFI embedded firmware, so as to not regress functionality in that case.

Driver for the external-charger IRQ pass-through function of the
Intel Bay Trail Crystal Cove PMIC.
Note this is NOT a power_supply class driver, it just deals with IRQ
pass-through, this requires this separate driver because the PMIC's
level 2 interrupt for this must be explicitly acked.
This new driver gets enabled by the existing X86_ANDROID_TABLETS Kconfig
option because the x86-android-tablets module is the only consumer of the
exported external-charger IRQ.

x86 tablets which ship with Android as (part of) the factory image
typically have various problems with their DSDTs. The factory kernels
shipped on these devices typically have device addresses and GPIOs
hardcoded in the kernel, rather then specified in their DSDT.
With the DSDT containing a random collection of devices which may or
may not actually be present as well as missing devices which are
actually present.
This driver, which loads only on affected models based on DMI matching,
adds DMI based instantiating of kernel devices for devices which are
missing from the DSDT, fixing e.g. battery monitoring, touchpads and/or
accelerometers not working.
Note the Kconfig help text also refers to "various fixes" ATM there are
no such fixes, but there are also known cases where entries are present
in the DSDT but they contain bugs, such as missing/wrong GPIOs. The plan
is to also add fixes for things like this here in the future.
This is the least ugly option to get these devices to fully work and to
do so without adding any extra code to the main kernel image (vmlinuz)
when built as a module.

In case device registration fails during module initialisation, the
platform device structure needs to be freed using platform_device_put()
to properly free all resources (e.g. the device name).

Siemens industrial PCs unfortunately can not always be properly
identified the way we used to. An earlier commit introduced code that
allows proper identification without looking at DMI strings that could
differ based on product branding.
Switch over to that proper way and revert commits that used to collect
the machines based on unstable strings.

This mainly implements detection of these devices and will allow
secondary drivers to work on such machines.
The identification is DMI-based with a vendor specific way to tell them
apart in a reliable way.
Drivers for LEDs and Watchdogs will follow to make use of that platform
detection.
There is also some code to allow secondary drivers to find GPIO memory,
that needs to be in place because the pinctrl drivers do not come up.

While introduction of this menu brings a nice view in the configuration tools,
it brought more issues than solves, i.e. it prevents to locate files in the
intel/ subfolder without touching non-related Kconfig dependencies elsewhere.
Drop X86_PLATFORM_DRIVERS_INTEL altogether.
Note, on x86 it's enabled by default and it's quite unlikely anybody wants to
disable all of the modules in this submenu.

Intel Platform Monitoring Technology (PMT) support is indicated by presence
of an Intel defined PCIe Designated Vendor Specific Extended Capabilities
(DVSEC) structure with a PMT specific ID. The current MFD implementation
creates child devices for each PMT feature, currently telemetry, watcher,
and crashlog. However DVSEC structures may also be used by Intel to
indicate support for other features. The Out Of Band Management Services
Module (OOBMSM) uses DVSEC to enumerate several features, including PMT.
In order to support them it is necessary to modify the intel_pmt driver to
handle the creation of the child devices more generically. To that end,
modify the driver to create child devices for any VSEC/DVSEC features on
supported devices (indicated by PCI ID). Additionally, move the
implementation from MFD to the Auxiliary bus. VSEC/DVSEC features are
really multifunctional PCI devices, not platform devices as MFD was
designed for. Auxiliary bus gives more flexibility by allowing the
definition of custom structures that can be shared between associated
auxiliary devices and the parent device. Also, rename the driver from
intel_pmt to intel_vsec to better reflect the purpose.
This series also removes the current runtime pm support which was not
complete to begin with. None of the current devices require runtime pm.
However the support will be replaced when a device is added that requires
it.

There needs to be a check to prevent negative offsets for
setting->index. I have reviewed this code and I think that the
"if (block->instance_count <= instance)" check in __query_block() will
prevent this from resulting in an out of bounds access. But it's
still worth fixing.

STB (Smart Trace Buffer), is a debug trace buffer that isolates the
failures by analyzing the last running feature of a system. This
non-intrusive way always runs in the background and stores the trace
into the SoC.
This patch enables the STB feature by passing module param
"enable_stb=1" while loading the driver and provides mechanism to
access the STB buffer using the read and write routines.
