+Freescale Reference Board Bindings
+
+This document describes device tree bindings for various devices that
+exist on some Freescale reference boards.
+
+* Board Control and Status (BCSR)
+
+Required properties:
+
+ - compatible : Should be "fsl,<board>-bcsr"
+ - reg : Offset and length of the register set for the device
+
+Example:
+
+ bcsr@f8000000 {
+ compatible = "fsl,mpc8360mds-bcsr";
+ reg = <f8000000 8000>;
+ };
+
+* Freescale on-board FPGA
+
+This is the memory-mapped registers for on board FPGA.
+
+Required properities:
+- compatible: should be a board-specific string followed by a string
+ indicating the type of FPGA. Example:
+ "fsl,<board>-fpga", "fsl,fpga-pixis"
+- reg: should contain the address and the length of the FPGA register set.
+- interrupt-parent: should specify phandle for the interrupt controller.
+- interrupts: should specify event (wakeup) IRQ.
+
+Example (P1022DS):
+
+ board-control@3,0 {
+ compatible = "fsl,p1022ds-fpga", "fsl,fpga-ngpixis";
+ reg = <3 0 0x30>;
+ interrupt-parent = <&mpic>;
+ interrupts = <8 8 0 0>;
+ };
+
+* Freescale BCSR GPIO banks
+
+Some BCSR registers act as simple GPIO controllers, each such
+register can be represented by the gpio-controller node.
+
+Required properities:
+- compatible : Should be "fsl,<board>-bcsr-gpio".
+- reg : Should contain the address and the length of the GPIO bank
+ register.
+- #gpio-cells : Should be two. The first cell is the pin number and the
+ second cell is used to specify optional parameters (currently unused).
+- gpio-controller : Marks the port as GPIO controller.
+
+Example:
+
+ bcsr@1,0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "fsl,mpc8360mds-bcsr";
+ reg = <1 0 0x8000>;
+ ranges = <0 1 0 0x8000>;
+
+ bcsr13: gpio-controller@d {
+ #gpio-cells = <2>;
+ compatible = "fsl,mpc8360mds-bcsr-gpio";
+ reg = <0xd 1>;
+ gpio-controller;
+ };
+ };

+* Freescale PQ3 and QorIQ based Cache SRAM
+
+Freescale's mpc85xx and some QorIQ platforms provide an
+option of configuring a part of (or full) cache memory
+as SRAM. This cache SRAM representation in the device
+tree should be done as under:-
+
+Required properties:
+
+- compatible : should be "fsl,p2020-cache-sram"
+- fsl,cache-sram-ctlr-handle : points to the L2 controller
+- reg : offset and length of the cache-sram.

+* Freescale Communications Processor Module
+
+NOTE: This is an interim binding, and will likely change slightly,
+as more devices are supported. The QE bindings especially are
+incomplete.
+
+* Root CPM node
+
+Properties:
+- compatible : "fsl,cpm1", "fsl,cpm2", or "fsl,qe".
+- reg : A 48-byte region beginning with CPCR.
+
+Example:
+ cpm@119c0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ #interrupt-cells = <2>;
+ compatible = "fsl,mpc8272-cpm", "fsl,cpm2";
+ reg = <119c0 30>;
+ }
+
+* Properties common to multiple CPM/QE devices
+
+- fsl,cpm-command : This value is ORed with the opcode and command flag
+ to specify the device on which a CPM command operates.
+
+- fsl,cpm-brg : Indicates which baud rate generator the device
+ is associated with. If absent, an unused BRG
+ should be dynamically allocated. If zero, the
+ device uses an external clock rather than a BRG.
+
+- reg : Unless otherwise specified, the first resource represents the
+ scc/fcc/ucc registers, and the second represents the device's
+ parameter RAM region (if it has one).
+
+* Multi-User RAM (MURAM)
+
+The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
+
+Ranges must be set up subject to the following restrictions:
+
+- Children's reg nodes must be offsets from the start of all muram, even
+ if the user-data area does not begin at zero.
+- If multiple range entries are used, the difference between the parent
+ address and the child address must be the same in all, so that a single
+ mapping can cover them all while maintaining the ability to determine
+ CPM-side offsets with pointer subtraction. It is recommended that
+ multiple range entries not be used.
+- A child address of zero must be translatable, even if no reg resources
+ contain it.
+
+A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
+indicate the portion of muram that is usable by the OS for arbitrary
+purposes. The data node may have an arbitrary number of reg resources,
+all of which contribute to the allocatable muram pool.
+
+Example, based on mpc8272:
+ muram@0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0 10000>;
+
+ data@0 {
+ compatible = "fsl,cpm-muram-data";
+ reg = <0 2000 9800 800>;
+ };
+ };

+* I2C
+
+The I2C controller is expressed as a bus under the CPM node.
+
+Properties:
+- compatible : "fsl,cpm1-i2c", "fsl,cpm2-i2c"
+- reg : On CPM2 devices, the second resource doesn't specify the I2C
+ Parameter RAM itself, but the I2C_BASE field of the CPM2 Parameter RAM
+ (typically 0x8afc 0x2).
+- #address-cells : Should be one. The cell is the i2c device address with
+ the r/w bit set to zero.
+- #size-cells : Should be zero.
+- clock-frequency : Can be used to set the i2c clock frequency. If
+ unspecified, a default frequency of 60kHz is being used.
+The following two properties are deprecated. They are only used by legacy
+i2c drivers to find the bus to probe:
+- linux,i2c-index : Can be used to hard code an i2c bus number. By default,
+ the bus number is dynamically assigned by the i2c core.
+- linux,i2c-class : Can be used to override the i2c class. The class is used
+ by legacy i2c device drivers to find a bus in a specific context like
+ system management, video or sound. By default, I2C_CLASS_HWMON (1) is
+ being used. The definition of the classes can be found in
+ include/i2c/i2c.h
+
+Example, based on mpc823:

+* Freescale QUICC Engine module (QE)
+This represents qe module that is installed on PowerQUICC II Pro.
+
+NOTE: This is an interim binding; it should be updated to fit
+in with the CPM binding later in this document.
+
+Basically, it is a bus of devices, that could act more or less
+as a complete entity (UCC, USB etc ). All of them should be siblings on
+the "root" qe node, using the common properties from there.
+The description below applies to the qe of MPC8360 and
+more nodes and properties would be extended in the future.
+
+i) Root QE device
+
+Required properties:
+- compatible : should be "fsl,qe";
+- model : precise model of the QE, Can be "QE", "CPM", or "CPM2"
+- reg : offset and length of the device registers.
+- bus-frequency : the clock frequency for QUICC Engine.
+- fsl,qe-num-riscs: define how many RISC engines the QE has.
+- fsl,qe-num-snums: define how many serial number(SNUM) the QE can use for the
+ threads.
+
+Optional properties:
+- fsl,firmware-phandle:
+ Usage: required only if there is no fsl,qe-firmware child node
+ Value type: <phandle>
+ Definition: Points to a firmware node (see "QE Firmware Node" below)
+ that contains the firmware that should be uploaded for this QE.
+ The compatible property for the firmware node should say,
+ "fsl,qe-firmware".
+
+Recommended properties
+- brg-frequency : the internal clock source frequency for baud-rate
+ generators in Hz.
+
+Example:
+ qe@e0100000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ #interrupt-cells = <2>;
+ compatible = "fsl,qe";
+ ranges = <0 e0100000 00100000>;
+ reg = <e0100000 480>;
+ brg-frequency = <0>;
+ bus-frequency = <179A7B00>;
+ }
+
+* Multi-User RAM (MURAM)
+
+Required properties:
+- compatible : should be "fsl,qe-muram", "fsl,cpm-muram".
+- mode : the could be "host" or "slave".
+- ranges : Should be defined as specified in 1) to describe the
+ translation of MURAM addresses.
+- data-only : sub-node which defines the address area under MURAM
+ bus that can be allocated as data/parameter
+
+Example:
+
+ muram@10000 {
+ compatible = "fsl,qe-muram", "fsl,cpm-muram";
+ ranges = <0 00010000 0000c000>;
+
+ data-only@0{
+ compatible = "fsl,qe-muram-data",
+ "fsl,cpm-muram-data";
+ reg = <0 c000>;
+ };
+ };
+
+* QE Firmware Node
+
+This node defines a firmware binary that is embedded in the device tree, for
+the purpose of passing the firmware from bootloader to the kernel, or from
+the hypervisor to the guest.
+
+The firmware node itself contains the firmware binary contents, a compatible
+property, and any firmware-specific properties. The node should be placed
+inside a QE node that needs it. Doing so eliminates the need for a
+fsl,firmware-phandle property. Other QE nodes that need the same firmware
+should define an fsl,firmware-phandle property that points to the firmware node
+in the first QE node.
+
+The fsl,firmware property can be specified in the DTS (possibly using incbin)
+or can be inserted by the boot loader at boot time.
+
+Required properties:
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: A standard property. Specify a string that indicates what
+ kind of firmware it is. For QE, this should be "fsl,qe-firmware".
+
+ - fsl,firmware
+ Usage: required
+ Value type: <prop-encoded-array>, encoded as an array of bytes
+ Definition: A standard property. This property contains the firmware
+ binary "blob".
+
+Example:
+ qe1@e0080000 {
+ compatible = "fsl,qe";
+ qe_firmware:qe-firmware {
+ compatible = "fsl,qe-firmware";
+ fsl,firmware = [0x70 0xcd 0x00 0x00 0x01 0x46 0x45 ...];
+ };
+ ...
+ };
+
+ qe2@e0090000 {
+ compatible = "fsl,qe";
+ fsl,firmware-phandle = <&qe_firmware>;
+ ...
+ };

+* Uploaded QE firmware
+
+ If a new firmware has been uploaded to the QE (usually by the

+* Parallel I/O Ports
+
+This node configures Parallel I/O ports for CPUs with QE support.
+The node should reside in the "soc" node of the tree. For each
+device that using parallel I/O ports, a child node should be created.
+See the definition of the Pin configuration nodes below for more
+information.
+
+Required properties:
+- device_type : should be "par_io".
+- reg : offset to the register set and its length.
+- num-ports : number of Parallel I/O ports
+
+Example:
+par_io@1400 {
+ reg = <1400 100>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ device_type = "par_io";
+ num-ports = <7>;
+ ucc_pin@01 {
+ ......
+ };
+
+Note that "par_io" nodes are obsolete, and should not be used for
+the new device trees. Instead, each Par I/O bank should be represented
+via its own gpio-controller node:
+
+Required properties:
+- #gpio-cells : should be "2".
+- compatible : should be "fsl,<chip>-qe-pario-bank",
+ "fsl,mpc8323-qe-pario-bank".
+- reg : offset to the register set and its length.
+- gpio-controller : node to identify gpio controllers.
+
+Example:
+ qe_pio_a: gpio-controller@1400 {
+ #gpio-cells = <2>;
+ compatible = "fsl,mpc8360-qe-pario-bank",
+ "fsl,mpc8323-qe-pario-bank";

+- compatible : could be "ucc_geth" or "fsl_atm" and so on.
+- cell-index : the ucc number(1-8), corresponding to UCCx in UM.
+- reg : Offset and length of the register set for the device
+- interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+- interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+- pio-handle : The phandle for the Parallel I/O port configuration.
+- port-number : for UART drivers, the port number to use, between 0 and 3.
+ This usually corresponds to the /dev/ttyQE device, e.g. <0> = /dev/ttyQE0.
+ The port number is added to the minor number of the device. Unlike the
+ CPM UART driver, the port-number is required for the QE UART driver.
+- soft-uart : for UART drivers, if specified this means the QE UART device
+ driver should use "Soft-UART" mode, which is needed on some SOCs that have
+ broken UART hardware. Soft-UART is provided via a microcode upload.

+ "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+The following two properties are deprecated. rx-clock has been replaced
+with rx-clock-name, and tx-clock has been replaced with tx-clock-name.
+Drivers that currently use the deprecated properties should continue to
+do so, in order to support older device trees, but they should be updated
+to check for the new properties first.
+- rx-clock : represents the UCC receive clock source.
+ 0x00 : clock source is disabled;
+ 0x1~0x10 : clock source is BRG1~BRG16 respectively;
+ 0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
+- tx-clock: represents the UCC transmit clock source;
+ 0x00 : clock source is disabled;

+
+Note on DMA channel compatible properties: The compatible property must say
+"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel" to be used by the Elo DMA
+driver (fsldma). Any DMA channel used by fsldma cannot be used by another
+DMA driver, such as the SSI sound drivers for the MPC8610. Therefore, any DMA
+channel that should be used for another driver should not use
+"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel". For the SSI drivers, for
+example, the compatible property should be "fsl,ssi-dma-channel". See ssi.txt
+for more information.

+- reg : Offset and length of the register set for the device
+- interrupts: IFC may have one or two interrupts. If two interrupt

+ - cell-index : Index of the PSC in hardware
+ - reg : Offset and length of the register set for the PSC device
+ - interrupts : <a b> where a is the interrupt number of the
+ PSC FIFO Controller and b is a field that represents an
+ encoding of the sense and level information for the interrupt.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+
+Recommended properties :
+ - fsl,rx-fifo-size : the size of the RX fifo slice (a multiple of 4)
+ - fsl,tx-fifo-size : the size of the TX fifo slice (a multiple of 4)

+<chip>-<device>[-<mode>]. The OS should be able to match a device driver
+to the device based solely on the compatible value. If two drivers
+match on the compatible list; the 'most compatible' driver should be
+selected.
+
+The split between the MPC5200 and the MPC5200B leaves a bit of a
+conundrum. How should the compatible property be set up to provide
+maximum compatibility information; but still accurately describe the
+chip? For the MPC5200; the answer is easy. Most of the SoC devices
+originally appeared on the MPC5200. Since they didn't exist anywhere
+else; the 5200 compatible properties will contain only one item;
+"fsl,mpc5200-<device>".
+
+The 5200B is almost the same as the 5200, but not quite. It fixes
+silicon bugs and it adds a small number of enhancements. Most of the
+devices either provide exactly the same interface as on the 5200. A few
+devices have extra functions but still have a backwards compatible mode.
+To express this information as completely as possible, 5200B device trees
+should have two items in the compatible list:
+ compatible = "fsl,mpc5200b-<device>","fsl,mpc5200-<device>";
+
+It is *strongly* recommended that 5200B device trees follow this convention
+(instead of only listing the base mpc5200 item).
+
+ie. ethernet on mpc5200: compatible = "fsl,mpc5200-fec";
+ ethernet on mpc5200b: compatible = "fsl,mpc5200b-fec", "fsl,mpc5200-fec";
+
+Modal devices, like PSCs, also append the configured function to the
+end of the compatible field. ie. A PSC in i2s mode would specify
+"fsl,mpc5200-psc-i2s", not "fsl,mpc5200-i2s". This convention is chosen to
+avoid naming conflicts with non-psc devices providing the same
+function. For example, "fsl,mpc5200-spi" and "fsl,mpc5200-psc-spi" describe
+the mpc5200 simple spi device and a PSC spi mode respectively.
+
+At the time of writing, exact chip may be either 'fsl,mpc5200' or
+'fsl,mpc5200b'.
+
+The soc node
+------------
+This node describes the on chip SOC peripherals. Every mpc5200 based
+board will have this node, and as such there is a common naming
+convention for SOC devices.
+
+Required properties:
+name description
+---- -----------
+ranges Memory range of the internal memory mapped registers.
+ Should be <0 [baseaddr] 0xc000>
+reg Should be <[baseaddr] 0x100>
+compatible mpc5200: "fsl,mpc5200-immr"
+ mpc5200b: "fsl,mpc5200b-immr"
+system-frequency 'fsystem' frequency in Hz; XLB, IPB, USB and PCI
+ clocks are derived from the fsystem clock.
+bus-frequency IPB bus frequency in Hz. Clock rate
+ used by most of the soc devices.
+
+soc child nodes
+---------------
+Any on chip SOC devices available to Linux must appear as soc5200 child nodes.
+
+Note: The tables below show the value for the mpc5200. A mpc5200b device
+tree should use the "fsl,mpc5200b-<device>","fsl,mpc5200-<device>" form.

+
+fsl,mpc5200-gpt nodes
+---------------------
+On the mpc5200 and 5200b, GPT0 has a watchdog timer function. If the board
+design supports the internal wdt, then the device node for GPT0 should
+include the empty property 'fsl,has-wdt'. Note that this does not activate
+the watchdog. The timer will function as a GPT if the timer api is used, and
+it will function as watchdog if the watchdog device is used. The watchdog
+mode has priority over the gpt mode, i.e. if the watchdog is activated, any
+gpt api call to this timer will fail with -EBUSY.
+
+If you add the property
+ fsl,wdt-on-boot = <n>;
+GPT0 will be marked as in-use watchdog, i.e. blocking every gpt access to it.
+If n>0, the watchdog is started with a timeout of n seconds. If n=0, the
+configuration of the watchdog is not touched. This is useful in two cases:
+- just mark GPT0 as watchdog, blocking gpt accesses, and configure it later;
+- do not touch a configuration assigned by the boot loader which supervises
+ the boot process itself.
+
+The watchdog will respect the CONFIG_WATCHDOG_NOWAYOUT option.
+
+An mpc5200-gpt can be used as a single line GPIO controller. To do so,
+add the following properties to the gpt node:
+ gpio-controller;
+ #gpio-cells = <2>;
+When referencing the GPIO line from another node, the first cell must always
+be zero and the second cell represents the gpio flags and described in the
+gpio device tree binding.
+
+An mpc5200-gpt can be used as a single line edge sensitive interrupt
+controller. To do so, add the following properties to the gpt node:
+ interrupt-controller;
+ #interrupt-cells = <1>;
+When referencing the IRQ line from another node, the cell represents the
+sense mode; 1 for edge rising, 2 for edge falling.
+
+fsl,mpc5200-psc nodes
+---------------------
+The PSCs should include a cell-index which is the index of the PSC in
+hardware. cell-index is used to determine which shared SoC registers to
+use when setting up PSC clocking. cell-index number starts at '0'. ie:
+ PSC1 has 'cell-index = <0>'
+ PSC4 has 'cell-index = <3>'
+
+PSC in i2s mode: The mpc5200 and mpc5200b PSCs are not compatible when in
+i2s mode. An 'mpc5200b-psc-i2s' node cannot include 'mpc5200-psc-i2s' in the
+compatible field.
+
+
+fsl,mpc5200-gpio and fsl,mpc5200-gpio-wkup nodes
+------------------------------------------------
+Each GPIO controller node should have the empty property gpio-controller and
+#gpio-cells set to 2. First cell is the GPIO number which is interpreted
+according to the bit numbers in the GPIO control registers. The second cell
+is for flags which is currently unused.
+
+fsl,mpc5200-fec nodes
+---------------------
+The FEC node can specify one of the following properties to configure
+the MII link:
+- fsl,7-wire-mode - An empty property that specifies the link uses 7-wire
+ mode instead of MII
+- current-speed - Specifies that the MII should be configured for a fixed
+ speed. This property should contain two cells. The
+ first cell specifies the speed in Mbps and the second
+ should be '0' for half duplex and '1' for full duplex
+- phy-handle - Contains a phandle to an Ethernet PHY.
+
+Interrupt controller (fsl,mpc5200-pic) node
+-------------------------------------------
+The mpc5200 pic binding splits hardware IRQ numbers into two levels. The
+split reflects the layout of the PIC hardware itself, which groups
+interrupts into one of three groups; CRIT, MAIN or PERP. Also, the
+Bestcomm dma engine has it's own set of interrupt sources which are
+cascaded off of peripheral interrupt 0, which the driver interprets as a
+fourth group, SDMA.
+
+The interrupts property for device nodes using the mpc5200 pic consists
+of three cells; <L1 L2 level>
+
+ L1 := [CRIT=0, MAIN=1, PERP=2, SDMA=3]
+ L2 := interrupt number; directly mapped from the value in the
+ "ICTL PerStat, MainStat, CritStat Encoded Register"
+ level := [LEVEL_HIGH=0, EDGE_RISING=1, EDGE_FALLING=2, LEVEL_LOW=3]
+
+For external IRQs, use the following interrupt property values (how to
+specify external interrupts is a frequently asked question):
+External interrupts:
+ external irq0: interrupts = <0 0 n>;
+ external irq1: interrupts = <1 1 n>;
+ external irq2: interrupts = <1 2 n>;
+ external irq3: interrupts = <1 3 n>;
+'n' is sense (0: level high, 1: edge rising, 2: edge falling 3: level low)

+* FSL MPIC Message Registers
+
+This binding specifies what properties must be available in the device tree
+representation of the message register blocks found in some FSL MPIC

+
+Required properties:
+
+ - compatible: Specifies the compatibility list for the message register
+ block. The type shall be <string-list> and the value shall be of the form

+ the MPIC containing the message registers.
+

+ cell is interrupt-number and second cell is level-sense. The type shall be
+ <prop-encoded-array>.
+
+Optional properties:
+
+ - mpic-msgr-receive-mask: Specifies what registers in the containing block

+ An alias should be created for every message register block. They are not
+ required, though. However, a particular implementation of this binding
+ may require aliases to be present. Aliases are of the form

+=====================================================================
+Freescale MPIC Interrupt Controller Node
+Copyright (C) 2010,2011 Freescale Semiconductor Inc.
+=====================================================================
+
+The Freescale MPIC interrupt controller is found on all PowerQUICC
+and QorIQ processors and is compatible with the Open PIC. The
+notable difference from Open PIC binding is the addition of 2
+additional cells in the interrupt specifier defining interrupt type
+information.
+
+PROPERTIES
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: Shall include "fsl,mpic". Freescale MPIC
+ controllers compatible with this binding have Block
+ Revision Registers BRR1 and BRR2 at offset 0x0 and
+ 0x10 in the MPIC.
+
+ - reg
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: A standard property. Specifies the physical
+ offset and length of the device's registers within the
+ CCSR address space.
+
+ - interrupt-controller
+ Usage: required
+ Value type: <empty>
+ Definition: Specifies that this node is an interrupt
+ controller
+
+ - #interrupt-cells
+ Usage: required
+ Value type: <u32>
+ Definition: Shall be 2 or 4. A value of 2 means that interrupt
+ specifiers do not contain the interrupt-type or type-specific
+ information cells.
+
+ - #address-cells
+ Usage: required
+ Value type: <u32>
+ Definition: Shall be 0.
+
+ - pic-no-reset
+ Usage: optional
+ Value type: <empty>
+ Definition: The presence of this property specifies that the
+ MPIC must not be reset by the client program, and that
+ the boot program has initialized all interrupt source
+ configuration registers to a sane state-- masked or
+ directed at other cores. This ensures that the client
+ program will not receive interrupts for sources not belonging
+ to the client. The presence of this property also mandates
+ that any initialization related to interrupt sources shall
+ be limited to sources explicitly referenced in the device tree.
+
+ - big-endian
+ Usage: optional
+ Value type: <empty>
+ If present the MPIC will be assumed to be big-endian. Some
+ device-trees omit this property on MPIC nodes even when the MPIC is
+ in fact big-endian, so certain boards override this property.
+
+ - single-cpu-affinity
+ Usage: optional
+ Value type: <empty>
+ If present the MPIC will be assumed to only be able to route
+ non-IPI interrupts to a single CPU at a time (EG: Freescale MPIC).
+
+ - last-interrupt-source
+ Usage: optional
+ Value type: <u32>
+ Some MPICs do not correctly report the number of hardware sources
+ in the global feature registers. If specified, this field will
+ override the value read from MPIC_GREG_FEATURE_LAST_SRC.
+
+INTERRUPT SPECIFIER DEFINITION
+
+ Interrupt specifiers consists of 4 cells encoded as
+ follows:
+
+ <1st-cell> interrupt-number
+
+ Identifies the interrupt source. The meaning
+ depends on the type of interrupt.
+
+ Note: If the interrupt-type cell is undefined
+ (i.e. #interrupt-cells = 2), this cell
+ should be interpreted the same as for
+ interrupt-type 0-- i.e. an external or
+ normal SoC device interrupt.
+
+ <2nd-cell> level-sense information, encoded as follows:
+ 0 = low-to-high edge triggered
+ 1 = active low level-sensitive
+ 2 = active high level-sensitive
+ 3 = high-to-low edge triggered
+
+ <3rd-cell> interrupt-type
+
+ The following types are supported:
+
+ 0 = external or normal SoC device interrupt
+
+ The interrupt-number cell contains
+ the SoC device interrupt number. The
+ type-specific cell is undefined. The
+ interrupt-number is derived from the
+ MPIC a block of registers referred to as
+ the "Interrupt Source Configuration Registers".
+ Each source has 32-bytes of registers
+ (vector/priority and destination) in this
+ region. So interrupt 0 is at offset 0x0,
+ interrupt 1 is at offset 0x20, and so on.
+
+ 1 = error interrupt
+
+ The interrupt-number cell contains
+ the SoC device interrupt number for
+ the error interrupt. The type-specific
+ cell identifies the specific error
+ interrupt number.
+
+ 2 = MPIC inter-processor interrupt (IPI)
+
+ The interrupt-number cell identifies
+ the MPIC IPI number. The type-specific
+ cell is undefined.
+
+ 3 = MPIC timer interrupt
+
+ The interrupt-number cell identifies
+ the MPIC timer number. The type-specific
+ cell is undefined.
+
+ <4th-cell> type-specific information
+
+ The type-specific cell is encoded as follows:
+
+ - For interrupt-type 1 (error interrupt),
+ the type-specific cell contains the
+ bit number of the error interrupt in the
+ Error Interrupt Summary Register.
+
+EXAMPLE 1
+ /*
+ * mpic interrupt controller with 4 cells per specifier
+ */
+ mpic: pic@40000 {

+* Freescale MSI interrupt controller
+
+Required properties:
+- compatible : compatible list, contains 2 entries,
+ first is "fsl,CHIP-msi", where CHIP is the processor(mpc8610, mpc8572,
+ etc.) and the second is "fsl,mpic-msi" or "fsl,ipic-msi" depending on
+ the parent type.
+
+- reg : It may contain one or two regions. The first region should contain
+ the address and the length of the shared message interrupt register set.
+ The second region should contain the address of aliased MSIIR register for
+ platforms that have such an alias.
+
+- msi-available-ranges: use <start count> style section to define which
+ msi interrupt can be used in the 256 msi interrupts. This property is
+ optional, without this, all the 256 MSI interrupts can be used.
+ Each available range must begin and end on a multiple of 32 (i.e.
+ no splitting an individual MSI register or the associated PIC interrupt).
+
+- interrupts : each one of the interrupts here is one entry per 32 MSIs,
+ and routed to the host interrupt controller. the interrupts should
+ be set as edge sensitive. If msi-available-ranges is present, only
+ the interrupts that correspond to available ranges shall be present.
+
+- interrupt-parent: the phandle for the interrupt controller
+ that services interrupts for this device. for 83xx cpu, the interrupts
+ are routed to IPIC, and for 85xx/86xx cpu the interrupts are routed
+ to MPIC.
+
+Optional properties:
+- msi-address-64: 64-bit PCI address of the MSIIR register. The MSIIR register
+ is used for MSI messaging. The address of MSIIR in PCI address space is
+ the MSI message address.
+
+ This property may be used in virtualized environments where the hypervisor
+ has created an alternate mapping for the MSIR block. See below for an
+ explanation.
+
+
+Example:
+ msi@41600 {
+ compatible = "fsl,mpc8610-msi", "fsl,mpic-msi";

+ 0xe3 0
+ 0xe4 0
+ 0xe5 0
+ 0xe6 0
+ 0xe7 0>;
+ interrupt-parent = <&mpic>;
+ };
+
+The Freescale hypervisor and msi-address-64
+-------------------------------------------
+Normally, PCI devices have access to all of CCSR via an ATMU mapping. The
+Freescale MSI driver calculates the address of MSIIR (in the MSI register
+block) and sets that address as the MSI message address.
+
+In a virtualized environment, the hypervisor may need to create an IOMMU
+mapping for MSIIR. The Freescale ePAPR hypervisor has this requirement
+because of hardware limitations of the Peripheral Access Management Unit
+(PAMU), which is currently the only IOMMU that the hypervisor supports.
+The ATMU is programmed with the guest physical address, and the PAMU
+intercepts transactions and reroutes them to the true physical address.
+
+In the PAMU, each PCI controller is given only one primary window. The
+PAMU restricts DMA operations so that they can only occur within a window.
+Because PCI devices must be able to DMA to memory, the primary window must
+be used to cover all of the guest's memory space.
+
+PAMU primary windows can be divided into 256 subwindows, and each
+subwindow can have its own address mapping ("guest physical" to "true
+physical"). However, each subwindow has to have the same alignment, which
+means they cannot be located at just any address. Because of these
+restrictions, it is usually impossible to create a 4KB subwindow that
+covers MSIIR where it's normally located.
+
+Therefore, the hypervisor has to create a subwindow inside the same
+primary window used for memory, but mapped to the MSIR block (where MSIIR
+lives). The first subwindow after the end of guest memory is used for

+Freescale Peripheral Management Access Unit (PAMU) Device Tree Binding
+
+DESCRIPTION
+
+The PAMU is an I/O MMU that provides device-to-memory access control and
+address translation capabilities.
+
+Required properties:
+
+- compatible : <string>
+ First entry is a version-specific string, such as
+ "fsl,pamu-v1.0". The second is "fsl,pamu".
+- ranges : <prop-encoded-array>
+ A standard property. Utilized to describe the memory mapped
+ I/O space utilized by the controller. The size should
+ be set to the total size of the register space of all
+ physically present PAMU controllers. For example, for
+ PAMU v1.0, on an SOC that has five PAMU devices, the size
+ is 0x5000.
+- interrupts : <prop-encoded-array>
+ Interrupt mappings. The first tuple is the normal PAMU
+ interrupt, used for reporting access violations. The second
+ is for PAMU hardware errors, such as PAMU operation errors
+ and ECC errors.
+- #address-cells: <u32>
+ A standard property.
+- #size-cells : <u32>
+ A standard property.
+
+Optional properties:
+- reg : <prop-encoded-array>
+ A standard property. It represents the CCSR registers of
+ all child PAMUs combined. Include it to provide support
+ for legacy drivers.
+- interrupt-parent : <phandle>
+ Phandle to interrupt controller
+
+Child nodes:
+
+Each child node represents one PAMU controller. Each SOC device that is
+connected to a specific PAMU device should have a "fsl,pamu-phandle" property
+that links to the corresponding specific child PAMU controller.
+
+- reg : <prop-encoded-array>
+ A standard property. Specifies the physical address and
+ length (relative to the parent 'ranges' property) of this
+ PAMU controller's configuration registers. The size should
+ be set to the size of this PAMU controllers's register space.
+ For PAMU v1.0, this size is 0x1000.
+- fsl,primary-cache-geometry
+ : <prop-encoded-array>
+ Two cells that specify the geometry of the primary PAMU
+ cache. The first is the number of cache lines, and the
+ second is the number of "ways". For direct-mapped caches,
+ specify a value of 1.
+- fsl,secondary-cache-geometry
+ : <prop-encoded-array>
+ Two cells that specify the geometry of the secondary PAMU
+ cache. The first is the number of cache lines, and the
+ second is the number of "ways". For direct-mapped caches,
+ specify a value of 1.
+
+Device nodes:
+
+Devices that have LIODNs need to specify links to the parent PAMU controller
+(the actual PAMU controller that this device is connected to) and a pointer to
+the LIODN register, if applicable.
+
+- fsl,iommu-parent
+ : <phandle>
+ Phandle to the single, specific PAMU controller node to which
+ this device is connect. The PAMU topology is represented in
+ the device tree to assist code that dynamically determines the
+ best LIODN values to minimize PAMU cache thrashing.
+
+- fsl,liodn-reg : <prop-encoded-array>
+ Two cells that specify the location of the LIODN register
+ for this device. Required for devices that have a single
+ LIODN. The first cell is a phandle to a node that contains
+ the registers where the LIODN is to be set. The second is
+ the offset from the first "reg" resource of the node where
+ the specific LIODN register is located.
+
+
+Example:

+ compatible = "fsl,pamu-v1.0", "fsl,pamu";
+ reg = <0x20000 0x5000>;

+ #address-cells = <1>;
+ #size-cells = <1>;

+* Power Management Controller
+
+Properties:
+- compatible: "fsl,<chip>-pmc".
+
+ "fsl,mpc8349-pmc" should be listed for any chip whose PMC is
+ compatible. "fsl,mpc8313-pmc" should also be listed for any chip
+ whose PMC is compatible, and implies deep-sleep capability.
+
+ "fsl,mpc8548-pmc" should be listed for any chip whose PMC is
+ compatible. "fsl,mpc8536-pmc" should also be listed for any chip
+ whose PMC is compatible, and implies deep-sleep capability.
+
+ "fsl,mpc8641d-pmc" should be listed for any chip whose PMC is
+ compatible; all statements below that apply to "fsl,mpc8548-pmc" also
+ apply to "fsl,mpc8641d-pmc".
+
+ Compatibility does not include bit assignments in SCCR/PMCDR/DEVDISR; these
+ bit assignments are indicated via the sleep specifier in each device's
+ sleep property.
+
+- reg: For devices compatible with "fsl,mpc8349-pmc", the first resource
+ is the PMC block, and the second resource is the Clock Configuration
+ block.
+
+ For devices compatible with "fsl,mpc8548-pmc", the first resource
+ is a 32-byte block beginning with DEVDISR.
+
+- interrupts: For "fsl,mpc8349-pmc"-compatible devices, the first
+ resource is the PMC block interrupt.
+
+- fsl,mpc8313-wakeup-timer: For "fsl,mpc8313-pmc"-compatible devices,
+ this is a phandle to an "fsl,gtm" node on which timer 4 can be used as
+ a wakeup source from deep sleep.
+
+Sleep specifiers:
+
+ fsl,mpc8349-pmc: Sleep specifiers consist of one cell. For each bit
+ that is set in the cell, the corresponding bit in SCCR will be saved
+ and cleared on suspend, and restored on resume. This sleep controller
+ supports disabling and resuming devices at any time.
+
+ fsl,mpc8536-pmc: Sleep specifiers consist of three cells, the third of
+ which will be ORed into PMCDR upon suspend, and cleared from PMCDR
+ upon resume. The first two cells are as described for fsl,mpc8578-pmc.
+ This sleep controller only supports disabling devices during system
+ sleep, or permanently.
+
+ fsl,mpc8548-pmc: Sleep specifiers consist of one or two cells, the
+ first of which will be ORed into DEVDISR (and the second into
+ DEVDISR2, if present -- this cell should be zero or absent if the
+ hardware does not have DEVDISR2) upon a request for permanent device
+ disabling. This sleep controller does not support configuring devices
+ to disable during system sleep (unless supported by another compatible
+ match), or dynamically.

+Freescale Synchronous Serial Interface
+
+The SSI is a serial device that communicates with audio codecs. It can
+be programmed in AC97, I2S, left-justified, or right-justified modes.
+
+Required properties:
+- compatible: Compatible list, contains "fsl,ssi".
+- cell-index: The SSI, <0> = SSI1, <1> = SSI2, and so on.
+- reg: Offset and length of the register set for the device.
+- interrupts: <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and
+ level information for the interrupt. This should be
+ encoded based on the information in section 2)
+ depending on the type of interrupt controller you
+ have.
+- interrupt-parent: The phandle for the interrupt controller that
+ services interrupts for this device.
+- fsl,mode: The operating mode for the SSI interface.
+ "i2s-slave" - I2S mode, SSI is clock slave
+ "i2s-master" - I2S mode, SSI is clock master
+ "lj-slave" - left-justified mode, SSI is clock slave
+ "lj-master" - l.j. mode, SSI is clock master
+ "rj-slave" - right-justified mode, SSI is clock slave
+ "rj-master" - r.j., SSI is clock master
+ "ac97-slave" - AC97 mode, SSI is clock slave
+ "ac97-master" - AC97 mode, SSI is clock master
+- fsl,playback-dma: Phandle to a node for the DMA channel to use for
+ playback of audio. This is typically dictated by SOC
+ design. See the notes below.
+- fsl,capture-dma: Phandle to a node for the DMA channel to use for
+ capture (recording) of audio. This is typically dictated
+ by SOC design. See the notes below.
+- fsl,fifo-depth: The number of elements in the transmit and receive FIFOs.
+ This number is the maximum allowed value for SFCSR[TFWM0].
+- fsl,ssi-asynchronous:
+ If specified, the SSI is to be programmed in asynchronous
+ mode. In this mode, pins SRCK, STCK, SRFS, and STFS must
+ all be connected to valid signals. In synchronous mode,
+ SRCK and SRFS are ignored. Asynchronous mode allows
+ playback and capture to use different sample sizes and
+ sample rates. Some drivers may require that SRCK and STCK
+ be connected together, and SRFS and STFS be connected
+ together. This would still allow different sample sizes,
+ but not different sample rates.
+
+Optional properties:
+- codec-handle: Phandle to a 'codec' node that defines an audio
+ codec connected to this SSI. This node is typically
+ a child of an I2C or other control node.
+
+Child 'codec' node required properties:
+- compatible: Compatible list, contains the name of the codec
+
+Child 'codec' node optional properties:
+- clock-frequency: The frequency of the input clock, which typically comes
+ from an on-board dedicated oscillator.

+Notes on fsl,playback-dma and fsl,capture-dma:
+
+On SOCs that have an SSI, specific DMA channels are hard-wired for playback
+and capture. On the MPC8610, for example, SSI1 must use DMA channel 0 for
+playback and DMA channel 1 for capture. SSI2 must use DMA channel 2 for
+playback and DMA channel 3 for capture. The developer can choose which
+DMA controller to use, but the channels themselves are hard-wired. The
+purpose of these two properties is to represent this hardware design.
+
+The device tree nodes for the DMA channels that are referenced by
+"fsl,playback-dma" and "fsl,capture-dma" must be marked as compatible with
+"fsl,ssi-dma-channel". The SOC-specific compatible string (e.g.
+"fsl,mpc8610-dma-channel") can remain. If these nodes are left as
+"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel", then the generic Elo DMA
+drivers (fsldma) will attempt to use them, and it will conflict with the
+sound drivers.
