+* ARM CPUs binding description
+
+The device tree allows to describe the layout of CPUs in a system through
+the "cpus" node, which in turn contains a number of subnodes (ie "cpu")
+defining properties for every cpu.
+
+Bindings for CPU nodes follow the ePAPR standard, available from:
+
+http://devicetree.org
+
+For the ARM architecture every CPU node must contain the following properties:
+
+- device_type: must be "cpu"
+- reg: property matching the CPU MPIDR[23:0] register bits
+ reg[31:24] bits must be set to 0
+- compatible: should be one of:
+ "arm,arm1020"
+ "arm,arm1020e"
+ "arm,arm1022"
+ "arm,arm1026"
+ "arm,arm720"

+* SPEAr Shared IRQ layer (shirq)
+
+SPEAr3xx architecture includes shared/multiplexed irqs for certain set
+of devices. The multiplexor provides a single interrupt to parent
+interrupt controller (VIC) on behalf of a group of devices.
+
+There can be multiple groups available on SPEAr3xx variants but not
+exceeding 4. The number of devices in a group can differ, further they
+may share same set of status/mask registers spanning across different
+bit masks. Also in some cases the group may not have enable or other
+registers. This makes software little complex.
+
+A single node in the device tree is used to describe the shared
+interrupt multiplexor (one node for all groups). A group in the
+interrupt controller shares config/control registers with other groups.
+For example, a 32-bit interrupt enable/disable config register can
+accommodate upto 4 interrupt groups.
+
+Required properties:
+ - compatible: should be, either of
+ - "st,spear300-shirq"
+ - "st,spear310-shirq"
+ - "st,spear320-shirq"
+ - interrupt-controller: Identifies the node as an interrupt controller.
+ - #interrupt-cells: should be <1> which basically contains the offset
+ (starting from 0) of interrupts for all the groups.
+ - reg: Base address and size of shirq registers.
+ - interrupts: The list of interrupts generated by the groups which are
+ then connected to a parent interrupt controller. Each group is
+ associated with one of the interrupts, hence number of interrupts (to
+ parent) is equal to number of groups. The format of the interrupt
+ specifier depends in the interrupt parent controller.
+
+ Optional properties:
+ - interrupt-parent: pHandle of the parent interrupt controller, if not
+ inherited from the parent node.
+
+Example:

+- reg : physical base address and the size of the registers window
+- gpio-controller : specifies that the node is a GPIO controller
+- #gpio-cells : size of the GPIO specifier, should be 2:

+* Core Clock bindings for Marvell MVEBU SoCs
+
+Marvell MVEBU SoCs usually allow to determine core clock frequencies by
+reading the Sample-At-Reset (SAR) register. The core clock consumer should
+specify the desired clock by having the clock ID in its "clocks" phandle cell.

+2.1) gpio-controller and pinctrl subsystem
+------------------------------------------
+gpio-controller on a SOC might be tightly coupled with the pinctrl
+subsystem, in the sense that the pins can be used by other functions
+together with optional gpio feature.
+
+While the pin allocation is totally managed by the pin ctrl subsystem,
+gpio (under gpiolib) is still maintained by gpio drivers. It may happen
+that different pin ranges in a SoC is managed by different gpio drivers.
+
+This makes it logical to let gpio drivers announce their pin ranges to
+the pin ctrl subsystem and call 'pinctrl_request_gpio' in order to
+request the corresponding pin before any gpio usage.
+
+For this, the gpio controller can use a pinctrl phandle and pins to
+announce the pinrange to the pin ctrl subsystem. For example,
+
+ qe_pio_e: gpio-controller@1460 {
+ #gpio-cells = <2>;
+ compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank";
+ reg = <0x1460 0x18>;
+ gpio-controller;
+ gpio-ranges = <&pinctrl1 20 10>, <&pinctrl2 50 20>;
+
+ }
+
+where,
+ &pinctrl1 and &pinctrl2 is the phandle to the pinctrl DT node.
+
+ Next values specify the base pin and number of pins for the range
+ handled by 'qe_pio_e' gpio. In the given example from base pin 20 to
+ pin 29 under pinctrl1 and pin 50 to pin 69 under pinctrl2 is handled
+ by this gpio controller.
+
+The pinctrl node must have "#gpio-range-cells" property to show number of
+arguments to pass with phandle from gpio controllers node.

+=== ST Microelectronics SPEAr SPI CS Driver ===
+
+SPEAr platform provides a provision to control chipselects of ARM PL022 Prime
+Cell spi controller through its system registers, which otherwise remains under
+PL022 control. If chipselect remain under PL022 control then they would be
+released as soon as transfer is over and TxFIFO becomes empty. This is not
+desired by some of the device protocols above spi which expect (multiple)
+transfers without releasing their chipselects.
+
+Chipselects can be controlled by software by turning them as GPIOs. SPEAr
+provides another interface through system registers through which software can
+directly control each PL022 chipselect. Hence, it is natural for SPEAr to export
+the control of this interface as gpio.
+
+Required properties:
+
+ * compatible: should be defined as "st,spear-spics-gpio"
+ * reg: mentioning address range of spics controller
+ * st-spics,peripcfg-reg: peripheral configuration register offset
+ * st-spics,sw-enable-bit: bit offset to enable sw control
+ * st-spics,cs-value-bit: bit offset to drive chipselect low or high
+ * st-spics,cs-enable-mask: chip select number bit mask
+ * st-spics,cs-enable-shift: chip select number program offset
+ * gpio-controller: Marks the device node as gpio controller
+ * #gpio-cells: should be 1 and will mention chip select number
+
+All the above bit offsets are within peripcfg register.

+GPIO-based I2C Bus Mux
+
+This binding describes an I2C bus multiplexer that uses GPIOs to
+route the I2C signals.
+
+ +-----+ +-----+
+ | dev | | dev |
+ +------------+ +-----+ +-----+
+ | SoC | | |
+ | | /--------+--------+
+ | +------+ | +------+ child bus A, on GPIO value set to 0

+ | | GPIO |-|-----+ +-----+ +-----+ +-----+
+ | +------+ | | dev | | dev | | dev |
+ +------------+ +-----+ +-----+ +-----+
+
+Required properties:
+- compatible: i2c-mux-gpio
+- i2c-parent: The phandle of the I2C bus that this multiplexer's master-side
+ port is connected to.
+- mux-gpios: list of gpios used to control the muxer
+* Standard I2C mux properties. See mux.txt in this directory.
+* I2C child bus nodes. See mux.txt in this directory.
+
+Optional properties:
+- idle-state: value to set the muxer to when idle. When no value is
+ given, it defaults to the last value used.
+
+For each i2c child node, an I2C child bus will be created. They will
+be numbered based on their order in the device tree.
+
+Whenever an access is made to a device on a child bus, the value set
+in the revelant node's reg property will be output using the list of
+GPIOs, the first in the list holding the least-significant value.
+
+If an idle state is defined, using the idle-state (optional) property,
+whenever an access is not being made to a device on a child bus, the
+GPIOs will be set according to the idle value.
+
+If an idle state is not defined, the most recently used value will be
+left programmed into hardware whenever no access is being made to a
+device on a child bus.
+
+Example:
+ i2cmux {
+ compatible = "i2c-mux-gpio";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ mux-gpios = <&gpio1 22 0 &gpio1 23 0>;

+* GPIO driven matrix keypad device tree bindings
+
+GPIO driven matrix keypad is used to interface a SoC with a matrix keypad.
+The matrix keypad supports multiple row and column lines, a key can be
+placed at each intersection of a unique row and a unique column. The matrix
+keypad can sense a key-press and key-release by means of GPIO lines and
+report the event using GPIO interrupts to the cpu.
+
+Required Properties:
+- compatible: Should be "gpio-matrix-keypad"
+- row-gpios: List of gpios used as row lines. The gpio specifier
+ for this property depends on the gpio controller to
+ which these row lines are connected.
+- col-gpios: List of gpios used as column lines. The gpio specifier
+ for this property depends on the gpio controller to
+ which these column lines are connected.
+- linux,keymap: The definition can be found at
+ bindings/input/matrix-keymap.txt
+
+Optional Properties:
+- linux,no-autorepeat: do no enable autorepeat feature.
+- linux,wakeup: use any event on keypad as wakeup event.
+- debounce-delay-ms: debounce interval in milliseconds
+- col-scan-delay-us: delay, measured in microseconds, that is needed
+ before we can scan keypad after activating column gpio
+
+Example:
+ matrix-keypad {
+ compatible = "gpio-matrix-keypad";

+* Atmel AT91 Pinmux Controller
+
+The AT91 Pinmux Controler, enables the IC
+to share one PAD to several functional blocks. The sharing is done by
+multiplexing the PAD input/output signals. For each PAD there are up to
+8 muxing options (called periph modes). Since different modules require
+different PAD settings (like pull up, keeper, etc) the contoller controls
+also the PAD settings parameters.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Atmel AT91 pin configuration node is a node of a group of pins which can be
+used for a specific device or function. This node represents both mux and config
+of the pins in that group. The 'pins' selects the function mode(also named pin
+mode) this pin can work on and the 'config' configures various pad settings
+such as pull-up, multi drive, etc.
+
+Required properties for iomux controller:
+- compatible: "atmel,at91rm9200-pinctrl"
+- atmel,mux-mask: array of mask (periph per bank) to describe if a pin can be
+ configured in this periph mode. All the periph and bank need to be describe.
+
+How to create such array:
+
+Each column will represent the possible peripheral of the pinctrl
+Each line will represent a pio bank
+
+Take an example on the 9260
+Peripheral: 2 ( A and B)
+Bank: 3 (A, B and C)

+
+ /* A B */
+ 0xffffffff 0xffc00c3b /* pioA */
+ 0xffffffff 0x7fff3ccf /* pioB */
+ 0xffffffff 0x007fffff /* pioC */
+
+For each peripheral/bank we will descibe in a u32 if a pin can can be
+configured in it by putting 1 to the pin bit (1 << pin)
+
+Let's take the pioA on peripheral B
+From the datasheet Table 10-2.

+Required properties for pin configuration node:
+- atmel,pins: 4 integers array, represents a group of pins mux and config
+ setting. The format is atmel,pins = <PIN_BANK PIN_BANK_NUM PERIPH CONFIG>.
+ The PERIPH 0 means gpio.
+
+Bits used for CONFIG:
+PULL_UP (1 << 0): indicate this pin need a pull up.
+MULTIDRIVE (1 << 1): indicate this pin need to be configured as multidrive.
+DEGLITCH (1 << 2): indicate this pin need deglitch.
+PULL_DOWN (1 << 3): indicate this pin need a pull down.
+DIS_SCHMIT (1 << 4): indicate this pin need to disable schmit trigger.
+DEBOUNCE (1 << 16): indicate this pin need debounce.
+DEBOUNCE_VAL (0x3fff << 17): debounce val.
+
+NOTE:
+Some requirements for using atmel,at91rm9200-pinctrl binding:
+1. We have pin function node defined under at91 controller node to represent
+ what pinmux functions this SoC supports.
+2. The driver can use the function node's name and pin configuration node's
+ name describe the pin function and group hierarchy.
+ For example, Linux at91 pinctrl driver takes the function node's name
+ as the function name and pin configuration node's name as group name to
+ create the map table.
+3. Each pin configuration node should have a phandle, devices can set pins
+ configurations by referring to the phandle of that pin configuration node.
+4. The gpio controller must be describe in the pinctrl simple-bus.

+
+Required properties:
+
+- compatible: Should contain "fsl,raideng-v1.0" as the value
+ This identifies RAID Engine block. 1 in 1.0 represents
+ major number whereas 0 represents minor number. The
+ version matches the hardware IP version.
+- reg: offset and length of the register set for the device
+- ranges: standard ranges property specifying the translation
+ between child address space and parent address space
+
+Example:
+ /* P5020 */
+ raideng: raideng@320000 {
+ compatible = "fsl,raideng-v1.0";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ reg = <0x320000 0x10000>;
+ ranges = <0 0x320000 0x10000>;
+ };
+
+
+There must be a sub-node for each job queue present in RAID Engine
+This node must be a sub-node of the main RAID Engine node
+
+- compatible: Should contain "fsl,raideng-v1.0-job-queue" as the value
+ This identifies the job queue interface
+- reg: offset and length of the register set for job queue
+- ranges: standard ranges property specifying the translation

+* Maxim MAX8997 Voltage and Current Regulator
+
+The Maxim MAX8997 is a multi-function device which includes volatage and
+current regulators, rtc, charger controller and other sub-blocks. It is
+interfaced to the host controller using a i2c interface. Each sub-block is
+addressed by the host system using different i2c slave address. This document
+describes the bindings for 'pmic' sub-block of max8997.
+
+Required properties:
+- compatible: Should be "maxim,max8997-pmic".
+- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
+
+- max8997,pmic-buck1-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
+ units for buck1 when changing voltage using gpio dvs. Refer to [1] below
+ for additional information.
+
+- max8997,pmic-buck2-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
+ units for buck2 when changing voltage using gpio dvs. Refer to [1] below
+ for additional information.
+
+- max8997,pmic-buck5-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
+ units for buck5 when changing voltage using gpio dvs. Refer to [1] below
+ for additional information.
+
+[1] If none of the 'max8997,pmic-buck[1/2/5]-uses-gpio-dvs' optional
+ property is specified, the 'max8997,pmic-buck[1/2/5]-dvs-voltage'
+ property should specify atleast one voltage level (which would be a
+ safe operating voltage).
+
+ If either of the 'max8997,pmic-buck[1/2/5]-uses-gpio-dvs' optional
+ property is specified, then all the eigth voltage values for the
+ 'max8997,pmic-buck[1/2/5]-dvs-voltage' should be specified.
+
+Optional properties:
+- interrupt-parent: Specifies the phandle of the interrupt controller to which
+ the interrupts from max8997 are delivered to.
+- interrupts: Interrupt specifiers for two interrupt sources.
+ - First interrupt specifier is for 'irq1' interrupt.
+ - Second interrupt specifier is for 'alert' interrupt.
+- max8997,pmic-buck1-uses-gpio-dvs: 'buck1' can be controlled by gpio dvs.
+- max8997,pmic-buck2-uses-gpio-dvs: 'buck2' can be controlled by gpio dvs.
+- max8997,pmic-buck5-uses-gpio-dvs: 'buck5' can be controlled by gpio dvs.
+
+Additional properties required if either of the optional properties are used:
+- max8997,pmic-ignore-gpiodvs-side-effect: When GPIO-DVS mode is used for
+ multiple bucks, changing the voltage value of one of the bucks may affect
+ that of another buck, which is the side effect of the change (set_voltage).
+ Use this property to ignore such side effects and change the voltage.
+
+- max8997,pmic-buck125-default-dvs-idx: Default voltage setting selected from
+ the possible 8 options selectable by the dvs gpios. The value of this
+ property should be between 0 and 7. If not specified or if out of range, the
+ default value of this property is set to 0.
+
+- max8997,pmic-buck125-dvs-gpios: GPIO specifiers for three host gpio's used
+ for dvs. The format of the gpio specifier depends in the gpio controller.
+
+Regulators: The regulators of max8997 that have to be instantiated should be
+included in a sub-node named 'regulators'. Regulator nodes included in this
+sub-node should be of the format as listed below.
+
+ regulator_name {
+ standard regulator bindings here
+ };
+
+The following are the names of the regulators that the max8997 pmic block
+supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
+as per the datasheet of max8997.
+
+ - LDOn
+ - valid values for n are 1 to 18 and 21
+ - Example: LDO0, LD01, LDO2, LDO21
+ - BUCKn
+ - valid values for n are 1 to 7.
+ - Example: BUCK1, BUCK2, BUCK3, BUCK7
+
+ - ENVICHG: Battery Charging Current Monitor Output. This is a fixed
+ voltage type regulator
+
+ - ESAFEOUT1: (ldo19)
+ - ESAFEOUT2: (ld020)
+
+ - CHARGER_CV: main battery charger voltage control
+ - CHARGER: main battery charger current control
+ - CHARGER_TOPOFF: end of charge current threshold level
+
+The bindings inside the regulator nodes use the standard regulator bindings
+which are documented elsewhere.
