-Most of the 64bit platforms have special hardware that translates bus
-addresses (DMA addresses) into physical addresses.  This is similar to
-how page tables and/or a TLB translates virtual addresses to physical
-addresses on a CPU.  This is needed so that e.g. PCI devices can
-access with a Single Address Cycle (32bit DMA address) any page in the
-64bit physical address space.  Previously in Linux those 64bit
-platforms had to set artificial limits on the maximum RAM size in the
-system, so that the virt_to_bus() static scheme works (the DMA address
-translation tables were simply filled on bootup to map each bus
-address to the physical page __pa(bus_to_virt())).
+                       CPU and DMA addresses
+
+There are several kinds of addresses involved in the DMA API, and it's
+important to understand the differences.
+
+The kernel normally uses virtual addresses.  Any address returned by
+kmalloc(), vmalloc(), and similar interfaces is a virtual address and can
+be stored in a "void *".
+
+The virtual memory system (TLB, page tables, etc.) translates virtual
+addresses to CPU physical addresses, which are stored as "phys_addr_t" or
+"resource_size_t".  The kernel manages device resources like registers as
+physical addresses.  These are the addresses in /proc/iomem.  The physical
+address is not directly useful to a driver; it must use ioremap() to map
+the space and produce a virtual address.
+
+I/O devices use a third kind of address: a "bus address" or "DMA address".
+If a device has registers at an MMIO address, or if it performs DMA to read
+or write system memory, the addresses used by the device are bus addresses.
+In some systems, bus addresses are identical to CPU physical addresses, but
+in general they are not.  IOMMUs and host bridges can produce arbitrary
+mappings between physical and bus addresses.
+
+Here's a picture and some examples:

+
+During the enumeration process, the kernel learns about I/O devices and
+their MMIO space and the host bridges that connect them to the system.  For
+example, if a PCI device has a BAR, the kernel reads the bus address (A)
+from the BAR and converts it to a CPU physical address (B).  The address B
+is stored in a struct resource and usually exposed via /proc/iomem.  When a
+driver claims a device, it typically uses ioremap() to map physical address
+B at a virtual address (C).  It can then use, e.g., ioread32(C), to access
+the device registers at bus address A.
+
+If the device supports DMA, the driver sets up a buffer using kmalloc() or
+a similar interface, which returns a virtual address (X).  The virtual
+memory system maps X to a physical address (Y) in system RAM.  The driver
+can use virtual address X to access the buffer, but the device itself
+cannot because DMA doesn't go through the CPU virtual memory system.
+
+In some simple systems, the device can do DMA directly to physical address
+Y.  But in many others, there is IOMMU hardware that translates bus
+addresses to physical addresses, e.g., it translates Z to Y.  This is part
+of the reason for the DMA API: the driver can give a virtual address X to
+an interface like dma_map_single(), which sets up any required IOMMU
+mapping and returns the bus address Z.  The driver then tells the device to
+do DMA to Z, and the IOMMU maps it to the buffer at address Y in system
+RAM.

+* Marvell Berlin2 chip control binding
+
+Marvell Berlin SoCs have a chip control register set providing several
+individual registers dealing with pinmux, padmux, clock, reset, and secondary
+CPU boot address. Unfortunately, the individual registers are spread among the
+chip control registers, so there should be a single DT node only providing the
+different functions which are described below.
+
+Required properties:
+- compatible: shall be one of
+	"marvell,berlin2-chip-ctrl" for BG2
+	"marvell,berlin2cd-chip-ctrl" for BG2CD
+	"marvell,berlin2q-chip-ctrl" for BG2Q
+- reg: address and length of following register sets for
+  BG2/BG2CD: chip control register set
+  BG2Q: chip control register set and cpu pll registers
+
+* Marvell Berlin2 system control binding
+
+Marvell Berlin SoCs have a system control register set providing several
+individual registers dealing with pinmux, padmux, and reset.
+
+Required properties:
+- compatible: should be one of
+	"marvell,berlin2-system-ctrl" for BG2
+	"marvell,berlin2cd-system-ctrl" for BG2CD
+	"marvell,berlin2q-system-ctrl" for BG2Q
+- reg: address and length of the system control register set
+
+* Clock provider binding
+
+As clock related registers are spread among the chip control registers, the
+chip control node also provides the clocks. Marvell Berlin2 (BG2, BG2CD, BG2Q)
+SoCs share the same IP for PLLs and clocks, with some minor differences in
+features and register layout.
+
+Required properties:
+- #clock-cells: shall be set to 1
+- clocks: clock specifiers referencing the core clock input clocks
+- clock-names: array of strings describing the input clock specifiers above.
+    Allowed clock-names for the reference clocks are
+      "refclk" for the SoCs osciallator input on all SoCs,
+    and SoC-specific input clocks for
+      BG2/BG2CD: "video_ext0" for the external video clock input
+
+Clocks provided by core clocks shall be referenced by a clock specifier
+indexing one of the provided clocks. Refer to dt-bindings/clock/berlin<soc>.h
+for the corresponding index mapping.
+
+* Pin controller binding
+
+Pin control registers are part of both register sets, chip control and system
+control. The pins controlled are organized in groups, so no actual pin
+information is needed.
+
+A pin-controller node should contain subnodes representing the pin group
+configurations, one per function. Each subnode has the group name and the muxing
+function used.
+
+Be aware the Marvell Berlin datasheets use the keyword 'mode' for what is called
+a 'function' in the pin-controller subsystem.
+
+Required subnode-properties:
+- groups: a list of strings describing the group names.
+- function: a string describing the function used to mux the groups.
+
+Example:
+
+chip: chip-control@ea0000 {
+	compatible = "marvell,berlin2-chip-ctrl";
+	#clock-cells = <1>;
+	reg = <0xea0000 0x400>;

+
+	spi1_pmux: spi1-pmux {
+		groups = "G0";
+		function = "spi1";

+* Generic PCI host controller
+
+Firmware-initialised PCI host controllers and PCI emulations, such as the
+virtio-pci implementations found in kvmtool and other para-virtualised
+systems, do not require driver support for complexities such as regulator
+and clock management. In fact, the controller may not even require the
+configuration of a control interface by the operating system, instead
+presenting a set of fixed windows describing a subset of IO, Memory and
+Configuration Spaces.
+
+Such a controller can be described purely in terms of the standardized device
+tree bindings communicated in pci.txt:
+
+
+Properties of the host controller node:
+
+- compatible     : Must be "pci-host-cam-generic" or "pci-host-ecam-generic"
+                   depending on the layout of configuration space (CAM vs
+                   ECAM respectively).
+
+- device_type    : Must be "pci".
+
+- ranges         : As described in IEEE Std 1275-1994, but must provide
+                   at least a definition of non-prefetchable memory. One
+                   or both of prefetchable Memory and IO Space may also
+                   be provided.
+
+- bus-range      : Optional property (also described in IEEE Std 1275-1994)
+                   to indicate the range of bus numbers for this controller.
+                   If absent, defaults to <0 255> (i.e. all buses).
+
+- #address-cells : Must be 3.
+
+- #size-cells    : Must be 2.
+
+- reg            : The Configuration Space base address and size, as accessed
+                   from the parent bus.
+
+
+Properties of the /chosen node:
+
+- linux,pci-probe-only
+                 : Optional property which takes a single-cell argument.
+                   If '0', then Linux will assign devices in its usual manner,
+                   otherwise it will not try to assign devices and instead use
+                   them as they are configured already.
+
+Configuration Space is assumed to be memory-mapped (as opposed to being
+accessed via an ioport) and laid out with a direct correspondence to the
+geography of a PCI bus address by concatenating the various components to
+form an offset.
+
+For CAM, this 24-bit offset is:
+
+        cfg_offset(bus, device, function, register) =
+                   bus << 16 | device << 11 | function << 8 | register
+
+Whilst ECAM extends this by 4 bits to accomodate 4k of function space:
+
+        cfg_offset(bus, device, function, register) =
+                   bus << 20 | device << 15 | function << 12 | register
+
+Interrupt mapping is exactly as described in `Open Firmware Recommended
+Practice: Interrupt Mapping' and requires the following properties:
+
+- #interrupt-cells   : Must be 1
+
+- interrupt-map      : <see aforementioned specification>
+
+- interrupt-map-mask : <see aforementioned specification>
+
+
+Example:
+
+pci {
+    compatible = "pci-host-cam-generic"
+    device_type = "pci";
+    #address-cells = <3>;
+    #size-cells = <2>;
+    bus-range = <0x0 0x1>;
+
+    // CPU_PHYSICAL(2)  SIZE(2)
+    reg = <0x0 0x40000000  0x0 0x1000000>;
+
+    // BUS_ADDRESS(3)  CPU_PHYSICAL(2)  SIZE(2)
+    ranges = <0x01000000 0x0 0x01000000  0x0 0x01000000  0x0 0x00010000>,
+             <0x02000000 0x0 0x41000000  0x0 0x41000000  0x0 0x3f000000>;
+
+
+    #interrupt-cells = <0x1>;
+
+    // PCI_DEVICE(3)  INT#(1)  CONTROLLER(PHANDLE)  CONTROLLER_DATA(3)
+    interrupt-map = <  0x0 0x0 0x0  0x1  &gic  0x0 0x4 0x1
+                     0x800 0x0 0x0  0x1  &gic  0x0 0x5 0x1

+Renesas AHB to PCI bridge
+-------------------------
+
+This is the bridge used internally to connect the USB controllers to the
+AHB. There is one bridge instance per USB port connected to the internal
+OHCI and EHCI controllers.
+
+Required properties:
+- compatible: "renesas,pci-r8a7790" for the R8A7790 SoC;
+	      "renesas,pci-r8a7791" for the R8A7791 SoC.
+- reg:	A list of physical regions to access the device: the first is
+	the operational registers for the OHCI/EHCI controllers and the
+	second is for the bridge configuration and control registers.
+- interrupts: interrupt for the device.
+- clocks: The reference to the device clock.
+- bus-range: The PCI bus number range; as this is a single bus, the range
+	     should be specified as the same value twice.
+- #address-cells: must be 3.
+- #size-cells: must be 2.
+- #interrupt-cells: must be 1.
+- interrupt-map: standard property used to define the mapping of the PCI

+configuration settings.  The mode setting will govern the input/output mode of
+the 4 GSBI IOs.
+
+Required properties:
+- compatible: must contain "qcom,gsbi-v1.0.0" for APQ8064/IPQ8064
+- reg: Address range for GSBI registers
+- clocks: required clock
+- clock-names: must contain "iface" entry
+- qcom,mode : indicates MUX value for configuration of the serial interface.
+  Please reference dt-bindings/soc/qcom,gsbi.h for valid mux values.
+
+Optional properties:
+- qcom,crci : indicates CRCI MUX value for QUP CRCI ports.  Please reference
+  dt-bindings/soc/qcom,gsbi.h for valid CRCI mux values.
+
+Required properties if child node exists:
+- #address-cells: Must be 1
+- #size-cells: Must be 1
+- ranges: Must be present
+
+Properties for children:
+
+A GSBI controller node can contain 0 or more child nodes representing serial
+devices.  These serial devices can be a QCOM UART, I2C controller, spi
+controller, or some combination of aforementioned devices.

@@ -73,6 +73,65 @@ The IRQ portions of the GPIO block are implemented using an irqchip, using
 the header <linux/irq.h>. So basically such a driver is utilizing two sub-
 systems simultaneously: gpio and irq.
 
+GPIO irqchips usually fall in one of two categories:
+
+* CHAINED GPIO irqchips: these are usually the type that is embedded on
+  an SoC. This means that there is a fast IRQ handler for the GPIOs that
+  gets called in a chain from the parent IRQ handler, most typically the
+  system interrupt controller. This means the GPIO irqchip is registered
+  using irq_set_chained_handler() or the corresponding
+  gpiochip_set_chained_irqchip() helper function, and the GPIO irqchip
+  handler will be called immediately from the parent irqchip, while
+  holding the IRQs disabled. The GPIO irqchip will then end up calling
+  something like this sequence in its interrupt handler:
+
+  static irqreturn_t tc3589x_gpio_irq(int irq, void *data)
+      chained_irq_enter(...);
+      generic_handle_irq(...);
+      chained_irq_exit(...);
+
+  Chained GPIO irqchips typically can NOT set the .can_sleep flag on
+  struct gpio_chip, as everything happens directly in the callbacks.
+
+* NESTED THREADED GPIO irqchips: these are off-chip GPIO expanders and any
+  other GPIO irqchip residing on the other side of a sleeping bus. Of course
+  such drivers that need slow bus traffic to read out IRQ status and similar,
+  traffic which may in turn incur other IRQs to happen, cannot be handled
+  in a quick IRQ handler with IRQs disabled. Instead they need to spawn a
+  thread and then mask the parent IRQ line until the interrupt is handled
+  by the driver. The hallmark of this driver is to call something like
+  this in its interrupt handler:
+
+  static irqreturn_t tc3589x_gpio_irq(int irq, void *data)
+      ...
+      handle_nested_irq(irq);
+
+  The hallmark of threaded GPIO irqchips is that they set the .can_sleep
+  flag on struct gpio_chip to true, indicating that this chip may sleep
+  when accessing the GPIOs.
+
+To help out in handling the set-up and management of GPIO irqchips and the
+associated irqdomain and resource allocation callbacks, the gpiolib has
+some helpers that can be enabled by selecting the GPIOLIB_IRQCHIP Kconfig
+symbol:
+
+* gpiochip_irqchip_add(): adds an irqchip to a gpiochip. It will pass
+  the struct gpio_chip* for the chip to all IRQ callbacks, so the callbacks
+  need to embed the gpio_chip in its state container and obtain a pointer
+  to the container using container_of().
+  (See Documentation/driver-model/design-patterns.txt)
+
+* gpiochip_set_chained_irqchip(): sets up a chained irq handler for a
+  gpio_chip from a parent IRQ and passes the struct gpio_chip* as handler
+  data. (Notice handler data, since the irqchip data is likely used by the
+  parent irqchip!) This is for the chained type of chip.
+
+To use the helpers please keep the following in mind:
+
+- Make sure to assign all relevant members of the struct gpio_chip so that
+  the irqchip can initialize. E.g. .dev and .can_sleep shall be set up
+  properly.
+
 It is legal for any IRQ consumer to request an IRQ from any irqchip no matter
 if that is a combined GPIO+IRQ driver. The basic premise is that gpio_chip and
 irq_chip are orthogonal, and offering their services independent of each

+HSI - High-speed Synchronous Serial Interface
+
+1. Introduction
+~~~~~~~~~~~~~~~
+
+High Speed Syncronous Interface (HSI) is a fullduplex, low latency protocol,
+that is optimized for die-level interconnect between an Application Processor
+and a Baseband chipset. It has been specified by the MIPI alliance in 2003 and
+implemented by multiple vendors since then.
+
+The HSI interface supports full duplex communication over multiple channels
+(typically 8) and is capable of reaching speeds up to 200 Mbit/s.
+
+The serial protocol uses two signals, DATA and FLAG as combined data and clock
+signals and an additional READY signal for flow control. An additional WAKE
+signal can be used to wakeup the chips from standby modes. The signals are
+commonly prefixed by AC for signals going from the application die to the
+cellular die and CA for signals going the other way around.
+

+2. HSI Subsystem in Linux
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In the Linux kernel the hsi subsystem is supposed to be used for HSI devices.
+The hsi subsystem contains drivers for hsi controllers including support for
+multi-port controllers and provides a generic API for using the HSI ports.
+
+It also contains HSI client drivers, which make use of the generic API to
+implement a protocol used on the HSI interface. These client drivers can
+use an arbitrary number of channels.
+
+3. hsi-char Device
+~~~~~~~~~~~~~~~~~~
+
+Each port automatically registers a generic client driver called hsi_char,
+which provides a charecter device for userspace representing the HSI port.
+It can be used to communicate via HSI from userspace. Userspace may
+configure the hsi_char device using the following ioctl commands:
+
+* HSC_RESET:
+ - flush the HSI port
+
+* HSC_SET_PM
+ - enable or disable the client.
+
+* HSC_SEND_BREAK
+ - send break
+
+* HSC_SET_RX
+ - set RX configuration
+
+* HSC_GET_RX
+ - get RX configuration
+
+* HSC_SET_TX
+ - set TX configuration
+
+* HSC_GET_TX
+ - get TX configuration

+ *			16B	32B	32B-F	48B	48B-2

+ * Channels		2	1/4	1	6	2/8

+ * Counter Width	16	32	32	32/48	32/48
+ * Shared Start/Stop	Y	Y	Y	Y	N
+ *
+ * The 48-bit gen2 version has a per-channel start/stop register located in the
+ * channel registers block. All other versions have a shared start/stop register
+ * located in the global space.
+ *
+ * Channels are indexed from 0 to N-1 in the documentation. The channel index
+ * infers the start/stop bit position in the control register and the channel
+ * registers block address. Some CMT instances have a subset of channels
+ * available, in which case the index in the documentation doesn't match the
+ * "real" index as implemented in hardware. This is for instance the case with
+ * CMT0 on r8a7740, which is a 32-bit variant with a single channel numbered 0
+ * in the documentation but using start/stop bit 5 and having its registers
+ * block at 0x60.
+ *
+ * Similarly CMT0 on r8a73a4, r8a7790 and r8a7791, while implementing 32-bit
+ * channels only, is a 48-bit gen2 CMT with the 48-bit channels unavailable.
