+Abilis Systems TB10x pin controller
+===================================
+
+Required properties
+-------------------
+
+- compatible: should be "abilis,tb10x-iomux";
+- reg: should contain the physical address and size of the pin controller's
+ register range.
+
+
+Function definitions
+--------------------
+
+Functions are defined (and referenced) by sub-nodes of the pin controller.
+Every sub-node defines exactly one function (implying a set of pins).
+Every function is associated to one named pin group inside the pin controller
+driver and these names are used to associate pin group predefinitions to pin
+controller sub-nodes.
+
+Required function definition subnode properties:
+ - abilis,function: should be set to the name of the function's pin group.
+
+The following pin groups are available:
+ - GPIO ports: gpioa, gpiob, gpioc, gpiod, gpioe, gpiof, gpiog,
+ gpioh, gpioi, gpioj, gpiok, gpiol, gpiom, gpion
+ - Serial TS input ports: mis0, mis1, mis2, mis3, mis4, mis5, mis6, mis7
+ - Parallel TS input ports: mip1, mip3, mip5, mip7
+ - Serial TS output ports: mos0, mos1, mos2, mos3
+ - Parallel TS output port: mop
+ - CI+ port: ciplus
+ - CableCard (Mcard) port: mcard
+ - Smart card ports: stc0, stc1
+ - UART ports: uart0, uart1
+ - SPI ports: spi1, spi3
+ - JTAG: jtag
+
+All other ports of the chip are not multiplexed and thus not managed by this
+driver.
+
+
+GPIO ranges definition
+----------------------
+
+The named pin groups of GPIO ports can be used to define GPIO ranges as
+explained in Documentation/devicetree/bindings/gpio/gpio.txt.
+
+
+Example
+-------
+
+iomux: iomux@ff10601c {
+ compatible = "abilis,tb10x-iomux";

+Actions Semi S900 Pin Controller
+
+This binding describes the pin controller found in the S900 SoC.
+
+Required Properties:
+
+- compatible: Should be "actions,s900-pinctrl"
+- reg: Should contain the register base address and size of
+ the pin controller.
+- clocks: phandle of the clock feeding the pin controller
+- gpio-controller: Marks the device node as a GPIO controller.
+- gpio-ranges: Specifies the mapping between gpio controller and
+ pin-controller pins.
+- #gpio-cells: Should be two. The first cell is the gpio pin number
+ and the second cell is used for optional parameters.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt. Shall be set to 2. The first cell
+ defines the interrupt number, the second encodes
+ the trigger flags described in
+ bindings/interrupt-controller/interrupts.txt
+- interrupts: The interrupt outputs from the controller. There is one GPIO
+ interrupt per GPIO bank. The number of interrupts listed depends
+ on the number of GPIO banks on the SoC. The interrupts must be
+ ordered by bank, starting with bank 0.
+
+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".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+Pinmux functions are available only for the pin groups while pinconf
+parameters are available for both pin groups and individual pins.
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+

+The pins controlled by sunXi pin controller are organized in banks,
+each bank has 32 pins. Each pin has 7 multiplexing functions, with
+the first two functions being GPIO in and out. The configuration on
+the pins includes drive strength and pull-up.
+
+Required properties:
+- compatible: Should be one of the following (depending on your SoC):

+ - "losc": the low frequency oscillator in the system
+
+Note: For backward compatibility reasons, the hosc and losc clocks are only
+required if you need to use the optional input-debounce property. Any new
+device tree should set them.
+
+Optional properties:
+ - input-debounce: Array of debouncing periods in microseconds. One period per
+ irq bank found in the controller. 0 if no setup required.
+
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices.
+
+A pinctrl node should contain at least one subnodes representing the
+pinctrl groups available on the machine. Each subnode will list the
+pins it needs, and how they should be configured, with regard to muxer
+configuration, drive strength and pullups. If one of these options is
+not set, its actual value will be unspecified.

+GPIO and interrupt controller
+-----------------------------
+
+This hardware also acts as a GPIO controller and an interrupt
+controller.
+
+Consumers that would want to refer to one or the other (or both)
+should provide through the usual *-gpios and interrupts properties a

+* Atmel AT91 Pinmux Controller
+
+The AT91 Pinmux Controller, 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 controller 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" or "atmel,at91sam9x5-pinctrl"
+ or "atmel,sama5d3-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

+
+For each peripheral/bank we will descibe in a u32 if a pin can be
+configured in it by putting 1 to the pin bit (1 << pin)

+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, PERIPH 1 is periph A, PERIPH 2 is periph B...
+ PIN_BANK 0 is pioA, PIN_BANK 1 is pioB...
+
+Bits used for CONFIG:
+PULL_UP (1 << 0): indicate this pin needs a pull up.
+MULTIDRIVE (1 << 1): indicate this pin needs to be configured as multi-drive.
+ Multi-drive is equivalent to open-drain type output.
+DEGLITCH (1 << 2): indicate this pin needs deglitch.
+PULL_DOWN (1 << 3): indicate this pin needs a pull down.
+DIS_SCHMIT (1 << 4): indicate this pin needs to the disable schmitt trigger.
+DRIVE_STRENGTH (3 << 5): indicate the drive strength of the pin using the
+ following values:
+ 00 - No change (reset state value kept)
+ 01 - Low
+ 10 - Medium
+ 11 - High
+OUTPUT (1 << 7): indicate this pin need to be configured as an output.
+OUTPUT_VAL (1 << 8): output val (1 = high, 0 = low)
+DEBOUNCE (1 << 16): indicate this pin needs debounce.
+DEBOUNCE_VAL (0x3fff << 17): debounce value.
+
+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.

+Broadcom BCM281xx Pin Controller
+
+This is a pin controller for the Broadcom BCM281xx SoC family, which includes
+BCM11130, BCM11140, BCM11351, BCM28145, and BCM28155 SoCs.
+
+=== Pin Controller Node ===
+
+Required Properties:
+
+- compatible: Must be "brcm,bcm11351-pinctrl"
+- reg: Base address of the PAD Controller register block and the size
+ of the block.
+
+For example, the following is the bare minimum node:
+
+ pinctrl@35004800 {
+ compatible = "brcm,bcm11351-pinctrl";
+ reg = <0x35004800 0x430>;
+ };
+
+As a pin controller device, in addition to the required properties, this node
+should also contain the pin configuration nodes that client devices reference,
+if any.
+
+=== Pin Configuration Node ===
+
+Each pin configuration node is a sub-node of the pin controller node and is a
+container of an arbitrary number of subnodes, called pin group nodes in this
+document.
+
+Please refer to the pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the definition of a
+"pin configuration node".
+
+=== Pin Group Node ===
+
+A pin group node specifies the desired pin mux and/or pin configuration for an
+arbitrary number of pins. The name of the pin group node is optional and not
+used.
+
+A pin group node only affects the properties specified in the node, and has no
+effect on any properties that are omitted.
+
+The pin group node accepts a subset of the generic pin config properties. For
+details generic pin config properties, please refer to pinctrl-bindings.txt
+and <include/linux/pinctrl/pinconfig-generic.h>.
+
+Each pin controlled by this pin controller belong to one of three types:
+Standard, I2C, and HDMI. Each type accepts a different set of pin config
+properties. A list of pins and their types is provided below.

+Example:
+// pin controller node
+pinctrl@35004800 {
+ compatible = "brcm,bcm11351-pinctrl";
+ reg = <0x35004800 0x430>;
+
+ // pin configuration node
+ dev_a_default: dev_a_active {
+ //group node defining 1 standard pin
+ grp_1 {
+ pins = "std_pin1";
+ function = "alt1";
+ input-schmitt-enable;
+ bias-disable;
+ slew-rate = <1>;
+ drive-strength = <4>;
+ };
+
+ // group node defining 2 I2C pins
+ grp_2 {
+ pins = "i2c_pin1", "i2c_pin2";
+ function = "alt2";
+ bias-pull-up = <720>;
+ input-enable;
+ };
+
+ // group node defining 2 HDMI pins
+ grp_3 {
+ pins = "hdmi_pin1", "hdmi_pin2";
+ function = "alt3";
+ slew-rate = <1>;
+ };
+
+ // other pin group nodes
+ ...
+ };
+
+ // other pin configuration nodes
+ ...
+};
+
+In the example above, "dev_a_active" is a pin configuration node with a number
+of sub-nodes. In the pin group node "grp_1", one pin, "std_pin1", is defined in
+the "pins" property. Thus, the remaining properties in the "grp_1" node applies
+only to this pin, including the following settings:
+ - setting pinmux to "alt1"
+ - enabling schmitt-trigger (hystersis) mode
+ - disabling pin bias
+ - setting the slew-rate to 1
+ - setting the drive strength to 4 mA
+Note that neither "input-enable" nor "input-disable" was specified - the pinctrl
+subsystem will therefore leave this property unchanged from whatever state it
+was in before applying these changes.
+
+The "pins" property in the pin group node "grp_2" specifies two pins -
+"i2c_pin1" and "i2c_pin2"; the remaining properties in this pin group node,
+therefore, applies to both of these pins. The properties include:
+ - setting pinmux to "alt2"
+ - setting pull-up resistance to 720 Ohm (ie. enabling 1.2k and 1.8k resistors
+ in parallel)
+ - enabling both pins' input
+"slew-rate" is not specified in this pin group node, so the slew-rate for these
+pins are left as-is.
+
+Finally, "grp_3" defines two HDMI pins. The following properties are applied to
+both pins:
+ - setting pinmux to "alt3"
+ - setting slew-rate to 1; for HDMI pins, this corresponds to the 3.4 Mbps
+ Highspeed mode
+The input is neither enabled or disabled, and is left untouched.

+Broadcom BCM2835 GPIO (and pinmux) controller
+
+The BCM2835 GPIO module is a combined GPIO controller, (GPIO) interrupt
+controller, and pinmux/control device.
+
+Required properties:
+- compatible: "brcm,bcm2835-gpio"
+- reg: Should contain the physical address of the GPIO module's registers.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two. The first cell is the pin number and the
+ second cell is used to specify optional parameters:
+ - bit 0 specifies polarity (0 for normal, 1 for inverted)
+- interrupts : The interrupt outputs from the controller. One interrupt per
+ individual bank followed by the "all banks" interrupt.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells : Should be 2.
+ The first cell is the GPIO number.
+ The second cell is used to specify flags:
+ bits[3:0] trigger type and level flags:
+ 1 = low-to-high edge triggered.
+ 2 = high-to-low edge triggered.
+ 4 = active high level-sensitive.
+ 8 = active low level-sensitive.
+ Valid combinations are 1, 2, 3, 4, 8.
+
+Please refer to ../gpio/gpio.txt for a general description of GPIO bindings.
+
+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".
+
+Each pin configuration node lists the pin(s) to which it applies, and one or
+more of the mux function to select on those pin(s), and pull-up/down
+configuration. Each subnode only affects those parameters that are explicitly
+listed. In other words, a subnode that lists only a mux function implies no
+information about any pull configuration. Similarly, a subnode that lists only
+a pul parameter implies no information about the mux function.
+
+The BCM2835 pin configuration and multiplexing supports the generic bindings.
+For details on each properties, you can refer to ./pinctrl-bindings.txt.
+
+Required sub-node properties:
+ - pins
+ - function
+
+Optional sub-node properties:
+ - bias-disable
+ - bias-pull-up
+ - bias-pull-down
+ - output-high
+ - output-low
+
+Legacy pin configuration and multiplexing binding:
+*** (Its use is deprecated, use generic multiplexing and configuration
+bindings instead)
+
+Required subnode-properties:
+- brcm,pins: An array of cells. Each cell contains the ID of a pin. Valid IDs
+ are the integer GPIO IDs; 0==GPIO0, 1==GPIO1, ... 53==GPIO53.
+
+Optional subnode-properties:
+- brcm,function: Integer, containing the function to mux to the pin(s):
+ 0: GPIO in
+ 1: GPIO out
+ 2: alt5
+ 3: alt4
+ 4: alt0
+ 5: alt1
+ 6: alt2
+ 7: alt3
+- brcm,pull: Integer, representing the pull-down/up to apply to the pin(s):
+ 0: none
+ 1: down
+ 2: up
+
+Each of brcm,function and brcm,pull may contain either a single value which
+will be applied to all pins in brcm,pins, or 1 value for each entry in
+brcm,pins.
+
+Example:
+
+ gpio: gpio {
+ compatible = "brcm,bcm2835-gpio";
+ reg = <0x2200000 0xb4>;
+ interrupts = <2 17>, <2 19>, <2 18>, <2 20>;

+ #gpio-cells = <2>;

+Conexant Digicolor CX92755 General Purpose Pin Mapping
+
+This document describes the device tree binding of the pin mapping hardware
+modules in the Conexant Digicolor CX92755 SoCs. The CX92755 in one of the
+Digicolor series of SoCs.
+
+=== Pin Controller Node ===
+
+Required Properties:
+
+- compatible: Must be "cnxt,cx92755-pinctrl"
+- reg: Base address of the General Purpose Pin Mapping register block and the
+ size of the block.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells: Must be <2>. The first cell is the pin number and the
+ second cell is used to specify flags. See include/dt-bindings/gpio/gpio.h
+ for possible values.
+
+For example, the following is the bare minimum node:
+
+ pinctrl: pinctrl@f0000e20 {
+ compatible = "cnxt,cx92755-pinctrl";
+ reg = <0xf0000e20 0x100>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+
+As a pin controller device, in addition to the required properties, this node
+should also contain the pin configuration nodes that client devices reference,
+if any.
+
+For a general description of GPIO bindings, please refer to ../gpio/gpio.txt.
+
+=== Pin Configuration Node ===
+
+Each pin configuration node is a sub-node of the pin controller node and is a
+container of an arbitrary number of subnodes, called pin group nodes in this
+document.
+
+Please refer to the pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the definition of a
+"pin configuration node".
+
+=== Pin Group Node ===
+
+A pin group node specifies the desired pin mux for an arbitrary number of
+pins. The name of the pin group node is optional and not used.
+
+A pin group node only affects the properties specified in the node, and has no
+effect on any properties that are omitted.
+
+The pin group node accepts a subset of the generic pin config properties. For
+details generic pin config properties, please refer to pinctrl-bindings.txt
+and <include/linux/pinctrl/pinconfig-generic.h>.
+
+Required Pin Group Node Properties:
+
+- pins: Multiple strings. Specifies the name(s) of one or more pins to be
+ configured by this node. The format of a pin name string is "GP_xy", where x
+ is an uppercase character from 'A' to 'R', and y is a digit from 0 to 7.
+- function: String. Specifies the pin mux selection. Values must be one of:
+ "gpio", "client_a", "client_b", "client_c"
+
+Example:
+ pinctrl: pinctrl@f0000e20 {
+ compatible = "cnxt,cx92755-pinctrl";
+ reg = <0xf0000e20 0x100>;
+
+ uart0_default: uart0_active {
+ data_signals {
+ pins = "GP_O0", "GP_O1";
+ function = "client_b";
+ };
+ };
+ };
+
+ uart0: uart@f0000740 {
+ compatible = "cnxt,cx92755-usart";
+ ...
+ pinctrl-0 = <&uart0_default>;
+ pinctrl-names = "default";
+ };
+
+In the example above, a single pin group configuration node defines the
+"client select" for the Rx and Tx signals of uart0. The uart0 node references
+that pin configuration node using the &uart0_default phandle.

+* Freescale IOMUX Controller (IOMUXC) for i.MX
+
+The IOMUX Controller (IOMUXC), together with the IOMUX, 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 ALT modes). Since different modules require
+different PAD settings (like pull up, keeper, etc) the IOMUXC 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".
+
+Freescale IMX 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 'mux' selects the function mode(also named mux
+mode) this pin can work on and the 'config' configures various pad settings
+such as pull-up, open drain, drive strength, etc.
+
+Required properties for iomux controller:
+- compatible: "fsl,<soc>-iomuxc"
+ Please refer to each fsl,<soc>-pinctrl.txt binding doc for supported SoCs.
+
+Required properties for pin configuration node:
+- fsl,pins: each entry consists of 6 integers and represents the mux and config
+ setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val
+ input_val> are specified using a PIN_FUNC_ID macro, which can be found in
+ imx*-pinfunc.h under device tree source folder. The last integer CONFIG is
+ the pad setting value like pull-up on this pin. And that's why fsl,pins entry
+ looks like <PIN_FUNC_ID CONFIG> in the example below.
+
+Bits used for CONFIG:
+NO_PAD_CTL(1 << 31): indicate this pin does not need config.
+
+SION(1 << 30): Software Input On Field.
+Force the selected mux mode input path no matter of MUX_MODE functionality.
+By default the input path is determined by functionality of the selected
+mux mode (regular).
+
+Other bits are used for PAD setting.
+Please refer to each fsl,<soc>-pinctrl,txt binding doc for SoC specific part
+of bits definitions.
+
+NOTE:
+Some requirements for using fsl,imx-pinctrl binding:
+1. We have pin function node defined under iomux controller node to represent
+ what pinmux functions this SoC supports.
+2. The pin configuration node intends to work on a specific function should
+ to be defined under that specific function node.
+ The function node's name should represent well about what function
+ this group of pins in this pin configuration node are working on.
+3. 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 IMX 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.
+4. Each pin configuration node should have a phandle, devices can set pins
+ configurations by referring to the phandle of that pin configuration node.
+
+Examples:
+usdhc@219c000 { /* uSDHC4 */
+ non-removable;
+ vmmc-supply = <&reg_3p3v>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_usdhc4_1>;
+};
+
+iomuxc@20e0000 {
+ compatible = "fsl,imx6q-iomuxc";
+ reg = <0x020e0000 0x4000>;
+
+ /* shared pinctrl settings */
+ usdhc4 {
+ pinctrl_usdhc4_1: usdhc4grp-1 {
+ fsl,pins = <
+ MX6QDL_PAD_SD4_CMD__SD4_CMD 0x17059
+ MX6QDL_PAD_SD4_CLK__SD4_CLK 0x10059
+ MX6QDL_PAD_SD4_DAT0__SD4_DATA0 0x17059

+ MX6QDL_PAD_SD4_DAT7__SD4_DATA7 0x17059
+ >;
+ };
+ ....
+};
+Refer to the IOMUXC controller chapter in imx6q datasheet,
+0x17059 means enable hysteresis, 47KOhm Pull Up, 50Mhz speed,
+80Ohm driver strength and Fast Slew Rate.
+User should refer to each SoC spec to set the correct value.

+* Freescale IMX27 IOMUX Controller
+
+Required properties:
+- compatible: "fsl,imx27-iomuxc"
+
+The iomuxc driver node should define subnodes containing of pinctrl configuration subnodes.
+
+Required properties for pin configuration node:
+- fsl,pins: three integers array, represents a group of pins mux and config
+ setting. The format is fsl,pins = <PIN MUX_ID CONFIG>.
+
+ PIN is an integer between 0 and 0xbf. imx27 has 6 ports with 32 configurable
+ configurable pins each. PIN is PORT * 32 + PORT_PIN, PORT_PIN is the pin
+ number on the specific port (between 0 and 31).
+
+ MUX_ID is
+ function + (direction << 2) + (gpio_oconf << 4) + (gpio_iconfa << 8) + (gpio_iconfb << 10)
+
+ function value is used to select the pin function.
+ Possible values:
+ 0 - Primary function
+ 1 - Alternate function
+ 2 - GPIO
+ Registers: GIUS (GPIO In Use), GPR (General Purpose Register)
+
+ direction defines the data direction of the pin.
+ Possible values:
+ 0 - Input
+ 1 - Output
+ Register: DDIR
+
+ gpio_oconf configures the gpio submodule output signal. This does not
+ have any effect unless GPIO function is selected. A/B/C_IN are output
+ signals of function blocks A,B and C. Specific function blocks are
+ described in the reference manual.
+ Possible values:
+ 0 - A_IN
+ 1 - B_IN
+ 2 - C_IN
+ 3 - Data Register
+ Registers: OCR1, OCR2
+
+ gpio_iconfa/b configures the gpio submodule input to functionblocks A and
+ B. GPIO function should be selected if this is configured.
+ Possible values:
+ 0 - GPIO_IN
+ 1 - Interrupt Status Register
+ 2 - Pulldown
+ 3 - Pullup
+ Registers ICONFA1, ICONFA2, ICONFB1 and ICONFB2
+
+ CONFIG can be 0 or 1, meaning Pullup disable/enable.
+
+
+The iomux controller has gpio child nodes which are embedded in the iomux
+control registers. They have to be defined as child nodes of the iomux device
+node. If gpio subnodes are defined "#address-cells", "#size-cells" and "ranges"
+properties for the iomux device node are required.
+
+Example:
+
+iomuxc: iomuxc@10015000 {
+ compatible = "fsl,imx27-iomuxc";
+ reg = <0x10015000 0x600>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ gpio1: gpio@10015000 {
+ ...
+ };
+
+ ...
+
+ uart {
+ pinctrl_uart1: uart-1 {
+ fsl,pins = <
+ 0x8c 0x004 0x0 /* UART1_TXD__UART1_TXD */
+ 0x8d 0x000 0x0 /* UART1_RXD__UART1_RXD */
+ 0x8e 0x004 0x0 /* UART1_CTS__UART1_CTS */
+ 0x8f 0x000 0x0 /* UART1_RTS__UART1_RTS */
+ >;
+ };
+
+ ...
+ };
+};
+
+
+For convenience there are macros defined in imx27-pinfunc.h which provide PIN
+and MUX_ID. They are structured as MX27_PAD_<Pad name>__<Signal name>. The names
+are defined in the i.MX27 reference manual.
+
+The above example using macros:
+
+iomuxc: iomuxc@10015000 {
+ compatible = "fsl,imx27-iomuxc";
+ reg = <0x10015000 0x600>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ gpio1: gpio@10015000 {
+ ...
+ };
+
+ ...
+
+ uart {
+ pinctrl_uart1: uart-1 {
+ fsl,pins = <
+ MX27_PAD_UART1_TXD__UART1_TXD 0x0
+ MX27_PAD_UART1_RXD__UART1_RXD 0x0
+ MX27_PAD_UART1_CTS__UART1_CTS 0x0
+ MX27_PAD_UART1_RTS__UART1_RTS 0x0
+ >;
+ };

+* Freescale MXS Pin Controller
+
+The pins controlled by mxs pin controller are organized in banks, each bank
+has 32 pins. Each pin has 4 multiplexing functions, and generally, the 4th
+function is GPIO. The configuration on the pins includes drive strength,
+voltage and pull-up.
+
+Required properties:
+- compatible: "fsl,imx23-pinctrl" or "fsl,imx28-pinctrl"
+- reg: Should contain the register physical address and length for the
+ pin controller.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices.
+
+The node of mxs pin controller acts as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for
+a group of pins, and only affects those parameters that are explicitly listed.
+In other words, a subnode that describes a drive strength parameter implies no
+information about pull-up. For this reason, even seemingly boolean values are
+actually tristates in this binding: unspecified, off, or on. Unspecified is
+represented as an absent property, and off/on are represented as integer
+values 0 and 1.
+
+Those subnodes under mxs pin controller node will fall into two categories.
+One is to set up a group of pins for a function, both mux selection and pin
+configurations, and it's called group node in the binding document. The other
+one is to adjust the pin configuration for some particular pins that need a
+different configuration than what is defined in group node. The binding
+document calls this type of node config node.
+
+On mxs, there is no hardware pin group. The pin group in this binding only
+means a group of pins put together for particular peripheral to work in
+particular function, like SSP0 functioning as mmc0-8bit. That said, the
+group node should include all the pins needed for one function rather than
+having these pins defined in several group nodes. It also means each of
+"pinctrl-*" phandle in client device node should only have one group node
+pointed in there, while the phandle can have multiple config node referenced
+there to adjust configurations for some pins in the group.
+
+Required subnode-properties:
+- fsl,pinmux-ids: An integer array. Each integer in the array specify a pin
+ with given mux function, with bank, pin and mux packed as below.
+
+ [15..12] : bank number
+ [11..4] : pin number
+ [3..0] : mux selection
+
+ This integer with mux selection packed is used as an entity by both group
+ and config nodes to identify a pin. The mux selection in the integer takes
+ effects only on group node, and will get ignored by driver with config node,
+ since config node is only meant to set up pin configurations.
+
+ Valid values for these integers are listed below.
+
+- reg: Should be the index of the group nodes for same function. This property
+ is required only for group nodes, and should not be present in any config
+ nodes.
+
+Optional subnode-properties:
+- fsl,drive-strength: Integer.
+ 0: MXS_DRIVE_4mA
+ 1: MXS_DRIVE_8mA
+ 2: MXS_DRIVE_12mA
+ 3: MXS_DRIVE_16mA
+- fsl,voltage: Integer.
+ 0: MXS_VOLTAGE_LOW - 1.8 V
+ 1: MXS_VOLTAGE_HIGH - 3.3 V
+- fsl,pull-up: Integer.
+ 0: MXS_PULL_DISABLE - Disable the internal pull-up
+ 1: MXS_PULL_ENABLE - Enable the internal pull-up
+
+Note that when enabling the pull-up, the internal pad keeper gets disabled.
+Also, some pins doesn't have a pull up, in that case, setting the fsl,pull-up
+will only disable the internal pad keeper.
+
+Examples:
+
+pinctrl@80018000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx28-pinctrl";
+ reg = <0x80018000 2000>;
+
+ mmc0_8bit_pins_a: mmc0-8bit@0 {
+ reg = <0>;
+ fsl,pinmux-ids = <
+ MX28_PAD_SSP0_DATA0__SSP0_D0
+ MX28_PAD_SSP0_DATA1__SSP0_D1
+ MX28_PAD_SSP0_DATA2__SSP0_D2
+ MX28_PAD_SSP0_DATA3__SSP0_D3
+ MX28_PAD_SSP0_DATA4__SSP0_D4
+ MX28_PAD_SSP0_DATA5__SSP0_D5
+ MX28_PAD_SSP0_DATA6__SSP0_D6
+ MX28_PAD_SSP0_DATA7__SSP0_D7
+ MX28_PAD_SSP0_CMD__SSP0_CMD
+ MX28_PAD_SSP0_DETECT__SSP0_CARD_DETECT
+ MX28_PAD_SSP0_SCK__SSP0_SCK
+ >;
+ fsl,drive-strength = <MXS_DRIVE_4mA>;
+ fsl,voltage = <MXS_VOLTAGE_HIGH>;
+ fsl,pull-up = <MXS_PULL_ENABLE>;
+ };
+
+ mmc_cd_cfg: mmc-cd-cfg {
+ fsl,pinmux-ids = <MX28_PAD_SSP0_DETECT__SSP0_CARD_DETECT>;
+ fsl,pull-up = <MXS_PULL_DISABLE>;
+ };
+
+ mmc_sck_cfg: mmc-sck-cfg {
+ fsl,pinmux-ids = <MX28_PAD_SSP0_SCK__SSP0_SCK>;
+ fsl,drive-strength = <MXS_DRIVE_12mA>;
+ fsl,pull-up = <MXS_PULL_DISABLE>;
+ };
+};
+
+In this example, group node mmc0-8bit defines a group of pins for mxs SSP0
+to function as a 8-bit mmc device, with 8mA, 3.3V and pull-up configurations
+applied on all these pins. And config nodes mmc-cd-cfg and mmc-sck-cfg are
+adjusting the configuration for pins card-detection and clock from what group
+node mmc0-8bit defines. Only the configuration properties to be adjusted need
+to be listed in the config nodes.
+
+Valid values for i.MX28/i.MX23 pinmux-id are defined in
+arch/arm/boot/dts/imx28-pinfunc.h and arch/arm/boot/dts/imx23-pinfunc.h.
+The definitions for the padconfig properties can be found in
+arch/arm/boot/dts/mxs-pinfunc.h.

+Ingenic jz47xx pin controller
+
+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".
+
+For the jz47xx SoCs, pin control is tightly bound with GPIO ports. All pins may
+be used as GPIOs, multiplexed device functions are configured within the
+GPIO port configuration registers and it is typical to refer to pins using the
+naming scheme "PxN" where x is a character identifying the GPIO port with
+which the pin is associated and N is an integer from 0 to 31 identifying the
+pin within that GPIO port. For example PA0 is the first pin in GPIO port A, and
+PB31 is the last pin in GPIO port B. The jz4740 contains 4 GPIO ports, PA to
+PD, for a total of 128 pins. The jz4780 contains 6 GPIO ports, PA to PF, for a
+total of 192 pins.
+
+
+Required properties:
+--------------------
+
+ - compatible: One of:
+ - "ingenic,jz4740-pinctrl"
+ - "ingenic,jz4770-pinctrl"
+ - "ingenic,jz4780-pinctrl"
+ - reg: Address range of the pinctrl registers.
+
+
+GPIO sub-nodes
+--------------
+
+The pinctrl node can have optional sub-nodes for the Ingenic GPIO driver;
+please refer to ../gpio/ingenic,gpio.txt.
+
+
+Example:
+--------
+
+pinctrl: pin-controller@10010000 {
+ compatible = "ingenic,jz4740-pinctrl";
+ reg = <0x10010000 0x400>;

+Lantiq FALCON pinmux controller

+ register range
+
+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".
+
+Lantiq's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those group(s), and two pin configuration parameters:
+pull-up and open-drain
+
+The name of each subnode is not important as long as it is unique; all subnodes
+should be enumerated and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+We support 2 types of nodes.
+
+Definition of mux function groups:
+
+Required subnode-properties:
+- lantiq,groups : An array of strings. Each string contains the name of a group.
+ Valid values for these names are listed below.
+- lantiq,function: A string containing the name of the function to mux to the
+ group. Valid values for function names are listed below.
+
+Valid values for group and function names:

+* Marvell Armada 37xx SoC pin and gpio controller
+
+Each Armada 37xx SoC come with two pin and gpio controller one for the
+south bridge and the other for the north bridge.
+
+Inside this set of register the gpio latch allows exposing some
+configuration of the SoC and especially the clock frequency of the
+xtal. Hence, this node is a represent as syscon allowing sharing the
+register between multiple hardware block.
+
+GPIO and pin controller:
+------------------------

+* Marvell SoC pinctrl core driver for mpp
+
+The pinctrl driver enables Marvell SoCs to configure the multi-purpose pins
+(mpp) to a specific function. For each SoC family there is a SoC specific
+driver using this core driver.
+
+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".
+
+A Marvell SoC pin configuration node is a node of a group of pins which can
+be used for a specific device or function. Each node requires one or more
+mpp pins or group of pins and a mpp function common to all pins.
+
+Required properties for pinctrl driver:
+- compatible: "marvell,<soc>-pinctrl"
+ Please refer to each marvell,<soc>-pinctrl.txt binding doc for supported SoCs.
+
+Required properties for pin configuration node:
+- marvell,pins: string array of mpp pins or group of pins to be muxed.
+- marvell,function: string representing a function to mux to for all
+ marvell,pins given in this pin configuration node. The function has to be
+ common for all marvell,pins. Please refer to marvell,<soc>-pinctrl.txt for
+ valid pin/pin group names and available function names for each SoC.
+
+Examples:
+
+uart1: serial@12100 {
+ compatible = "ns16550a";
+ reg = <0x12100 0x100>;
+ reg-shift = <2>;
+ interrupts = <7>;
+
+ pinctrl-0 = <&pmx_uart1_sw>;
+ pinctrl-names = "default";
+};
+
+pinctrl: pinctrl@d0200 {
+ compatible = "marvell,dove-pinctrl";
+ reg = <0xd0200 0x14>, <0xd0440 0x04>, <0xd802c 0x08>;
+
+ pmx_uart1_sw: pmx-uart1-sw {
+ marvell,pins = "mpp_uart1";
+ marvell,function = "uart1";
+ };
+};

+ - reg: address and size of registers controlling irq functionality
+
+=== GPIO sub-nodes ===
+
+The GPIO bank for the controller is represented as a sub-node and it acts as a
+GPIO controller.
+
+Required properties for sub-nodes are:
+ - reg: should contain address and size for mux, pull-enable, pull and
+ gpio register sets
+ - reg-names: an array of strings describing the "reg" entries. Must
+ contain "mux", "pull" and "gpio". "pull-enable" is optional and
+ when it is missing the "pull" registers are used instead
+ - gpio-controller: identifies the node as a gpio controller
+ - #gpio-cells: must be 2
+
+=== Other sub-nodes ===
+
+Child nodes without the "gpio-controller" represent some desired
+configuration for a pin or a group. Those nodes can be pinmux nodes or
+configuration nodes.
+
+Required properties for pinmux nodes are:
+ - groups: a list of pinmux groups. The list of all available groups
+ depends on the SoC and can be found in driver sources.
+ - function: the name of a function to activate for the specified set
+ of groups. The list of all available functions depends on the SoC
+ and can be found in driver sources.
+
+Required properties for configuration nodes:
+ - pins: a list of pin names
+
+Configuration nodes support the generic properties "bias-disable",
+"bias-pull-up" and "bias-pull-down", described in file
+pinctrl-bindings.txt
+
+=== Example ===
+
+ pinctrl: pinctrl@c1109880 {

+Device tree binding for NVIDIA Tegra DPAUX pad controller
+========================================================
+
+The Tegra Display Port Auxiliary (DPAUX) pad controller manages two pins
+which can be assigned to either the DPAUX channel or to an I2C
+controller.
+
+This document defines the device-specific binding for the DPAUX pad
+controller. Refer to pinctrl-bindings.txt in this directory for generic
+information about pin controller device tree bindings. Please refer to
+the binding document ../display/tegra/nvidia,tegra20-host1x.txt for more
+details on the DPAUX binding.
+
+Pin muxing:
+-----------
+
+Child nodes contain the pinmux configurations following the conventions
+from the pinctrl-bindings.txt document.
+
+Since only three configurations are possible, only three child nodes are
+needed to describe the pin mux'ing options for the DPAUX pads.
+Furthermore, given that the pad functions are only applicable to a
+single set of pads, the child nodes only need to describe the pad group
+the functions are being applied to rather than the individual pads.
+
+Required properties:
+- groups: Must be "dpaux-io"
+- function: Must be either "aux", "i2c" or "off".
+
+Example:
+--------
+
+ dpaux@545c0000 {
+ ...
+
+ state_dpaux_aux: pinmux-aux {
+ groups = "dpaux-io";
+ function = "aux";

+Device tree binding for NVIDIA Tegra XUSB pad controller
+========================================================
+
+NOTE: It turns out that this binding isn't an accurate description of the XUSB
+pad controller. While the description is good enough for the functional subset
+required for PCIe and SATA, it lacks the flexibility to represent the features
+needed for USB. For the new binding, see ../phy/nvidia,tegra-xusb-padctl.txt.
+The binding described in this file is deprecated and should not be used.
+
+The Tegra XUSB pad controller manages a set of lanes, each of which can be
+assigned to one out of a set of different pads. Some of these pads have an
+associated PHY that must be powered up before the pad can be used.
+
+This document defines the device-specific binding for the XUSB pad controller.
+
+Refer to pinctrl-bindings.txt in this directory for generic information about
+pin controller device tree bindings and ../phy/phy-bindings.txt for details on
+how to describe and reference PHYs in device trees.
+
+Required properties:
+--------------------
+- compatible: For Tegra124, must contain "nvidia,tegra124-xusb-padctl".
+ Otherwise, must contain '"nvidia,<chip>-xusb-padctl",
+ "nvidia-tegra124-xusb-padctl"', where <chip> is tegra132 or tegra210.
+- reg: Physical base address and length of the controller's registers.
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - padctl
+- #phy-cells: Should be 1. The specifier is the index of the PHY to reference.
+ See <dt-bindings/pinctrl/pinctrl-tegra-xusb.h> for the list of valid values.
+
+Lane muxing:
+------------
+
+Child nodes contain the pinmux configurations following the conventions from
+the pinctrl-bindings.txt document. Typically a single, static configuration is
+given and applied at boot time.
+
+Each subnode describes groups of lanes along with parameters and pads that
+they should be assigned to. The name of these subnodes is not important. All
+subnodes should be parsed solely based on their content.
+
+Each subnode only applies the parameters that are explicitly listed. In other
+words, if a subnode that lists a function but no pin configuration parameters
+implies no information about any pin configuration parameters. Similarly, a
+subnode that describes only an IDDQ parameter implies no information about
+what function the pins are assigned to. For this reason even seemingly boolean
+values are actually tristates in this binding: unspecified, off or on.
+Unspecified is represented as an absent property, and off/on are represented
+as integer values 0 and 1.
+
+Required properties:
+- nvidia,lanes: An array of strings. Each string is the name of a lane.
+
+Optional properties:
+- nvidia,function: A string that is the name of the function (pad) that the
+ pin or group should be assigned to. Valid values for function names are
+ listed below.
+- nvidia,iddq: Enables IDDQ mode of the lane. (0: no, 1: yes)
+
+Note that not all of these properties are valid for all lanes. Lanes can be
+divided into three groups:
+
+ - otg-0, otg-1, otg-2:
+
+ Valid functions for this group are: "snps", "xusb", "uart", "rsvd".
+
+ The nvidia,iddq property does not apply to this group.
+
+ - ulpi-0, hsic-0, hsic-1:
+
+ Valid functions for this group are: "snps", "xusb".
+
+ The nvidia,iddq property does not apply to this group.
+
+ - pcie-0, pcie-1, pcie-2, pcie-3, pcie-4, sata-0:
+
+ Valid functions for this group are: "pcie", "usb3", "sata", "rsvd".
+

+NVIDIA Tegra20 pinmux controller
+
+Required properties:
+- compatible: "nvidia,tegra20-pinmux"
+- reg: Should contain the register physical address and length for each of
+ the tri-state, mux, pull-up/down, and pad control register sets.
+
+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".
+
+Tegra's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, tristate, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function or tristate parameter. For this
+reason, even seemingly boolean values are actually tristates in this binding:
+unspecified, off, or on. Unspecified is represented as an absent property,
+and off/on are represented as integer values 0 and 1.
+
+Required subnode-properties:
+- nvidia,pins : An array of strings. Each string contains the name of a pin or
+ group. Valid values for these names are listed below.
+
+Optional subnode-properties:
+- nvidia,function: A string containing the name of the function to mux to the
+ pin or group. Valid values for function names are listed below. See the Tegra
+ TRM to determine which are valid for each pin or group.
+- nvidia,pull: Integer, representing the pull-down/up to apply to the pin.
+ 0: none, 1: down, 2: up.
+- nvidia,tristate: Integer.
+ 0: drive, 1: tristate.
+- nvidia,high-speed-mode: Integer. Enable high speed mode the pins.
+ 0: no, 1: yes.
+- nvidia,schmitt: Integer. Enables Schmitt Trigger on the input.
+ 0: no, 1: yes.
+- nvidia,low-power-mode: Integer. Valid values 0-3. 0 is least power, 3 is
+ most power. Controls the drive power or current. See "Low Power Mode"
+ or "LPMD1" and "LPMD0" in the Tegra TRM.
+- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest.
+ The range of valid values depends on the pingroup. See "CAL_DRVDN" in the
+ Tegra TRM.
+- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest.
+ The range of valid values depends on the pingroup. See "CAL_DRVUP" in the
+ Tegra TRM.
+- nvidia,slew-rate-rising: Integer. Controls rising signal slew rate. 0 is
+ fastest. The range of valid values depends on the pingroup. See
+ "DRVDN_SLWR" in the Tegra TRM.
+- nvidia,slew-rate-falling: Integer. Controls falling signal slew rate. 0 is
+ fastest. The range of valid values depends on the pingroup. See
+ "DRVUP_SLWF" in the Tegra TRM.
+
+Note that many of these properties are only valid for certain specific pins
+or groups. See the Tegra TRM and various pinmux spreadsheets for complete
+details regarding which groups support which functionality. The Linux pinctrl
+driver may also be a useful reference, since it consolidates, disambiguates,
+and corrects data from all those sources.

+NVIDIA Tegra30 pinmux controller
+
+The Tegra30 pinctrl binding is very similar to the Tegra20 pinctrl binding,
+as described in nvidia,tegra20-pinmux.txt. In fact, this document assumes
+that binding as a baseline, and only documents the differences between the
+two bindings.
+
+Required properties:
+- compatible: "nvidia,tegra30-pinmux"
+- reg: Should contain the register physical address and length for each of
+ the pad control and mux registers.
+
+Tegra30 adds the following optional properties for pin configuration subnodes:
+- nvidia,enable-input: Integer. Enable the pin's input path. 0: no, 1: yes.
+- nvidia,open-drain: Integer. Enable open drain mode. 0: no, 1: yes.
+- nvidia,lock: Integer. Lock the pin configuration against further changes
+ until reset. 0: no, 1: yes.
+- nvidia,io-reset: Integer. Reset the IO path. 0: no, 1: yes.
+
+As with Tegra20, see the Tegra TRM for complete details regarding which groups
+support which functionality.
+
+Valid values for pin and group names are:
+
+ per-pin mux groups:
+
+ These all support nvidia,function, nvidia,tristate, nvidia,pull,
+ nvidia,enable-input, nvidia,lock. Some support nvidia,open-drain,
+ nvidia,io-reset.

+== Introduction ==
+
+Hardware modules that control pin multiplexing or configuration parameters
+such as pull-up/down, tri-state, drive-strength etc are designated as pin
+controllers. Each pin controller must be represented as a node in device tree,
+just like any other hardware module.
+
+Hardware modules whose signals are affected by pin configuration are
+designated client devices. Again, each client device must be represented as a
+node in device tree, just like any other hardware module.
+
+For a client device to operate correctly, certain pin controllers must
+set up certain specific pin configurations. Some client devices need a
+single static pin configuration, e.g. set up during initialization. Others
+need to reconfigure pins at run-time, for example to tri-state pins when the
+device is inactive. Hence, each client device can define a set of named
+states. The number and names of those states is defined by the client device's
+own binding.
+
+The common pinctrl bindings defined in this file provide an infrastructure
+for client device device tree nodes to map those state names to the pin
+configuration used by those states.
+
+Note that pin controllers themselves may also be client devices of themselves.
+For example, a pin controller may set up its own "active" state when the
+driver loads. This would allow representing a board's static pin configuration
+in a single place, rather than splitting it across multiple client device
+nodes. The decision to do this or not somewhat rests with the author of
+individual board device tree files, and any requirements imposed by the
+bindings for the individual client devices in use by that board, i.e. whether
+they require certain specific named states for dynamic pin configuration.
+
+== Pinctrl client devices ==
+
+For each client device individually, every pin state is assigned an integer
+ID. These numbers start at 0, and are contiguous. For each state ID, a unique
+property exists to define the pin configuration. Each state may also be
+assigned a name. When names are used, another property exists to map from
+those names to the integer IDs.
+
+Each client device's own binding determines the set of states that must be
+defined in its device tree node, and whether to define the set of state
+IDs that must be provided, or whether to define the set of state names that
+must be provided.
+
+Required properties:
+pinctrl-0: List of phandles, each pointing at a pin configuration
+ node. These referenced pin configuration nodes must be child
+ nodes of the pin controller that they configure. Multiple
+ entries may exist in this list so that multiple pin
+ controllers may be configured, or so that a state may be built
+ from multiple nodes for a single pin controller, each
+ contributing part of the overall configuration. See the next
+ section of this document for details of the format of these
+ pin configuration nodes.
+
+ In some cases, it may be useful to define a state, but for it
+ to be empty. This may be required when a common IP block is
+ used in an SoC either without a pin controller, or where the
+ pin controller does not affect the HW module in question. If
+ the binding for that IP block requires certain pin states to
+ exist, they must still be defined, but may be left empty.
+
+Optional properties:
+pinctrl-1: List of phandles, each pointing at a pin configuration
+ node within a pin controller.
+...
+pinctrl-n: List of phandles, each pointing at a pin configuration
+ node within a pin controller.
+pinctrl-names: The list of names to assign states. List entry 0 defines the
+ name for integer state ID 0, list entry 1 for state ID 1, and
+ so on.
+
+For example:
+
+ /* For a client device requiring named states */
+ device {
+ pinctrl-names = "active", "idle";
+ pinctrl-0 = <&state_0_node_a>;
+ pinctrl-1 = <&state_1_node_a &state_1_node_b>;
+ };
+
+ /* For the same device if using state IDs */
+ device {
+ pinctrl-0 = <&state_0_node_a>;
+ pinctrl-1 = <&state_1_node_a &state_1_node_b>;
+ };
+
+ /*
+ * For an IP block whose binding supports pin configuration,
+ * but in use on an SoC that doesn't have any pin control hardware
+ */
+ device {
+ pinctrl-names = "active", "idle";
+ pinctrl-0 = <>;
+ pinctrl-1 = <>;
+ };
+
+== Pin controller devices ==
+Required properties: See the pin controller driver specific documentation
+
+Optional properties:
+#pinctrl-cells: Number of pin control cells in addition to the index within the
+ pin controller device instance
+
+pinctrl-use-default: Boolean. Indicates that the OS can use the boot default
+ pin configuration. This allows using an OS that does not have a
+ driver for the pin controller. This property can be set either
+ globally for the pin controller or in child nodes for individual
+ pin group control.
+
+Pin controller devices should contain the pin configuration nodes that client
+devices reference.
+
+For example:
+
+ pincontroller {
+ ... /* Standard DT properties for the device itself elided */
+
+ state_0_node_a {
+ ...
+ };
+ state_1_node_a {
+ ...
+ };
+ state_1_node_b {
+ ...
+ };
+ }
+
+The contents of each of those pin configuration child nodes is defined
+entirely by the binding for the individual pin controller device. There
+exists no common standard for this content. The pinctrl framework only
+provides generic helper bindings that the pin controller driver can use.
+
+The pin configuration nodes need not be direct children of the pin controller
+device; they may be grandchildren, for example. Whether this is legal, and
+whether there is any interaction between the child and intermediate parent
+nodes, is again defined entirely by the binding for the individual pin
+controller device.
+
+== Generic pin multiplexing node content ==
+
+pin multiplexing nodes:
+
+function - the mux function to select
+groups - the list of groups to select with this function
+ (either this or "pins" must be specified)
+pins - the list of pins to select with this function (either
+ this or "groups" must be specified)
+
+Example:
+
+state_0_node_a {
+ uart0 {
+ function = "uart0";
+ groups = "u0rxtx", "u0rtscts";
+ };
+};
+state_1_node_a {
+ spi0 {
+ function = "spi0";
+ groups = "spi0pins";
+ };
+};
+state_2_node_a {
+ function = "i2c0";
+ pins = "mfio29", "mfio30";
+};
+
+Optionally an alternative binding can be used if more suitable depending on the
+pin controller hardware. For hardware where there is a large number of identical
+pin controller instances, naming each pin and function can easily become
+unmaintainable. This is especially the case if the same controller is used for
+different pins and functions depending on the SoC revision and packaging.
+
+For cases like this, the pin controller driver may use pinctrl-pin-array helper
+binding with a hardware based index and a number of pin configuration values:
+
+pincontroller {
+ ... /* Standard DT properties for the device itself elided */
+ #pinctrl-cells = <2>;
+
+ state_0_node_a {
+ pinctrl-pin-array = <
+ 0 A_DELAY_PS(0) G_DELAY_PS(120)
+ 4 A_DELAY_PS(0) G_DELAY_PS(360)
+ ...
+ >;
+ };
+ ...
+};
+
+Above #pinctrl-cells specifies the number of value cells in addition to the
+index of the registers. This is similar to the interrupts-extended binding with
+one exception. There is no need to specify the phandle for each entry as that
+is already known as the defined pins are always children of the pin controller
+node. Further having the phandle pointing to another pin controller would not
+currently work as the pinctrl framework uses named modes to group pins for each
+pin control device.
+
+The index for pinctrl-pin-array must relate to the hardware for the pinctrl
+registers, and must not be a virtual index of pin instances. The reason for
+this is to avoid mapping of the index in the dts files and the pin controller
+driver as it can change.
+
+For hardware where pin multiplexing configurations have to be specified for
+each single pin the number of required sub-nodes containing "pin" and
+"function" properties can quickly escalate and become hard to write and
+maintain.
+
+For cases like this, the pin controller driver may use the pinmux helper
+property, where the pin identifier is provided with mux configuration settings
+in a pinmux group. A pinmux group consists of the pin identifier and mux
+settings represented as a single integer or an array of integers.
+
+The pinmux property accepts an array of pinmux groups, each of them describing
+a single pin multiplexing configuration.
+
+pincontroller {
+ state_0_node_a {
+ pinmux = <PINMUX_GROUP>, <PINMUX_GROUP>, ...;
+ };
+};
+
+Each individual pin controller driver bindings documentation shall specify
+how pin IDs and pin multiplexing configuration are defined and assembled
+together in a pinmux group.
+
+== Generic pin configuration node content ==
+
+Many data items that are represented in a pin configuration node are common
+and generic. Pin control bindings should use the properties defined below
+where they are applicable; not all of these properties are relevant or useful
+for all hardware or binding structures. Each individual binding document
+should state which of these generic properties, if any, are used, and the
+structure of the DT nodes that contain these properties.
+
+Supported generic properties are:
+
+pins - the list of pins that properties in the node
+ apply to (either this, "group" or "pinmux" has to be
+ specified)
+group - the group to apply the properties to, if the driver
+ supports configuration of whole groups rather than
+ individual pins (either this, "pins" or "pinmux" has
+ to be specified)
+pinmux - the list of numeric pin ids and their mux settings
+ that properties in the node apply to (either this,
+ "pins" or "groups" have to be specified)
+bias-disable - disable any pin bias
+bias-high-impedance - high impedance mode ("third-state", "floating")
+bias-bus-hold - latch weakly
+bias-pull-up - pull up the pin
+bias-pull-down - pull down the pin
+bias-pull-pin-default - use pin-default pull state
+drive-push-pull - drive actively high and low
+drive-open-drain - drive with open drain
+drive-open-source - drive with open source
+drive-strength - sink or source at most X mA
+input-enable - enable input on pin (no effect on output, such as
+ enabling an input buffer)
+input-disable - disable input on pin (no effect on output, such as
+ disabling an input buffer)
+input-schmitt-enable - enable schmitt-trigger mode
+input-schmitt-disable - disable schmitt-trigger mode
+input-debounce - debounce mode with debound time X
+power-source - select between different power supplies
+low-power-enable - enable low power mode
+low-power-disable - disable low power mode
+output-disable - disable output on a pin (such as disable an output
+ buffer)
+output-enable - enable output on a pin without actively driving it
+ (such as enabling an output buffer)
+output-low - set the pin to output mode with low level
+output-high - set the pin to output mode with high level
+sleep-hardware-state - indicate this is sleep related state which will be programmed
+ into the registers for the sleep state.
+slew-rate - set the slew rate
+skew-delay - this affects the expected clock skew on input pins
+ and the delay before latching a value to an output
+ pin. Typically indicates how many double-inverters are
+ used to delay the signal.
+
+For example:
+
+state_0_node_a {
+ cts_rxd {
+ pins = "GPIO0_AJ5", "GPIO2_AH4"; /* CTS+RXD */
+ bias-pull-up;
+ };
+};
+state_1_node_a {
+ rts_txd {
+ pins = "GPIO1_AJ3", "GPIO3_AH3"; /* RTS+TXD */
+ output-high;
+ };
+};
+state_2_node_a {
+ foo {
+ group = "foo-group";
+ bias-pull-up;
+ };
+};
+state_3_node_a {
+ mux {
+ pinmux = <GPIOx_PINm_MUXn>, <GPIOx_PINj_MUXk)>;
+ input-enable;
+ };
+};
+
+Some of the generic properties take arguments. For those that do, the
+arguments are described below.
+
+- pins takes a list of pin names or IDs as a required argument. The specific
+ binding for the hardware defines:
+ - Whether the entries are integers or strings, and their meaning.
+
+- pinmux takes a list of pin IDs and mux settings as required argument. The
+ specific bindings for the hardware defines:
+ - How pin IDs and mux settings are defined and assembled together in a single
+ integer or an array of integers.
+
+- bias-pull-up, -down and -pin-default take as optional argument on hardware
+ supporting it the pull strength in Ohm. bias-disable will disable the pull.
+
+- drive-strength takes as argument the target strength in mA.
+
+- input-debounce takes the debounce time in usec as argument
+ or 0 to disable debouncing
+
+More in-depth documentation on these parameters can be found in

+ chips - as the name suggests. Multiple SPI chips can share the same
+ SPI chipselect. Set a bit in bit0-7 in this mask to 1 if there is a
+ chip connected with the corresponding spi address set. For example if
+ you have a chip with address 3 connected, you have to set bit3 to 1,
+ which is 0x08. mcp23s08 chip variant only supports bits 0-3. It is not
+ possible to mix mcp23s08 and mcp23s17 on the same chipselect. Set at
+ least one bit to 1 for SPI chips.
+ NOTE: Do not use the old mcp prefix any more. It is deprecated and will be
+ removed.
+- spi-max-frequency = The maximum frequency this chip is able to handle
+
+Optional properties:
+- #interrupt-cells : Should be two.
+ - first cell is the pin number
+ - second cell is used to specify flags.
+- interrupt-controller: Marks the device node as a interrupt controller.
+- drive-open-drain: Sets the ODR flag in the IOCON register. This configures
+ the IRQ output as open drain active low.
+
+Optional device specific properties:
+- microchip,irq-mirror: Sets the mirror flag in the IOCON register. Devices
+ with two interrupt outputs (these are the devices ending with 17 and
+ those that have 16 IOs) have two IO banks: IO 0-7 form bank 1 and
+ IO 8-15 are bank 2. These chips have two different interrupt outputs:
+ One for bank 1 and another for bank 2. If irq-mirror is set, both
+ interrupts are generated regardless of the bank that an input change
+ occurred on. If it is not set, the interrupt are only generated for the
+ bank they belong to.
+ On devices with only one interrupt output this property is useless.
+- microchip,irq-active-high: Sets the INTPOL flag in the IOCON register. This
+ configures the IRQ output polarity as active high.
+
+Example I2C (with interrupt):
+gpiom1: gpio@20 {
+ compatible = "microchip,mcp23017";
+ gpio-controller;
+ #gpio-cells = <2>;
+ reg = <0x20>;
+
+ interrupt-parent = <&gpio1>;
+ interrupts = <17 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-controller;
+ #interrupt-cells=<2>;
+ microchip,irq-mirror;
+};
+
+Example SPI:
+gpiom1: gpio@0 {
+ compatible = "microchip,mcp23s17";
+ gpio-controller;
+ #gpio-cells = <2>;
+ spi-present-mask = <0x01>;
+ reg = <0>;
+ spi-max-frequency = <1000000>;
+};
+
+Pull-up configuration
+=====================
+
+If pins are used as output, they can also be configured with pull-ups. This is
+done with pinctrl.
+
+Please refer file <devicetree/bindings/pinctrl/pinctrl-bindings.txt>
+for details of the common pinctrl bindings used by client devices,
+including the meaning of the phrase "pin configuration node".
+
+Optional Pinmux properties:
+--------------------------
+Following properties are required if default setting of pins are required
+at boot.
+- pinctrl-names: A pinctrl state named per <pinctrl-bindings.txt>.
+- pinctrl[0...n]: Properties to contain the phandle for pinctrl states per
+ <pinctrl-bindings.txt>.
+
+The pin configurations are defined as child of the pinctrl states node. Each
+sub-node have following properties:
+
+Required properties:
+------------------
+- pins: List of pins. Valid values of pins properties are:
+ gpio0 ... gpio7 for the devices with 8 GPIO pins and
+ gpio0 ... gpio15 for the devices with 16 GPIO pins.
+
+Optional properties:
+-------------------
+The following optional property is defined in the pinmux DT binding document
+<pinctrl-bindings.txt>. Absence of this property will leave the configuration
+in its default state.
+ bias-pull-up
+
+Example with pinctrl to pull-up output pins:
+gpio21: gpio@21 {
+ compatible = "microchip,mcp23017";
+ gpio-controller;
+ #gpio-cells = <0x2>;
+ reg = <0x21>;
+ interrupt-parent = <&socgpio>;

+ #interrupt-cells = <0x2>;
+ microchip,irq-mirror;
+ pinctrl-names = "default";

+Subnode format
+A pinctrl node should contain at least one subnodes representing the
+pinctrl groups available on the machine. Each subnode will list the
+pins it needs, and how they should be configured, with regard to muxer
+configuration, pullups, drive strength, input enable/disable and input schmitt.
+
+ node {

+ GENERIC_PINCONFIG;
+ };
+
+Required properties:
+- pinmux: integer array, represents gpio pin number and mux setting.
+ Supported pin number and mux varies for different SoCs, and are defined
+ as macros in boot/dts/<soc>-pinfunc.h directly.
+
+Optional properties:

+ bias-pull-down, bias-pull-up, input-enable, input-disable, output-low, output-high,
+ input-schmitt-enable, input-schmitt-disable and drive-strength are valid.
+
+ Some special pins have extra pull up strength, there are R0 and R1 pull-up
+ resistors available, but for user, it's only need to set R1R0 as 00, 01, 10 or 11.
+ So when config bias-pull-up, it support arguments for those special pins.

+ "mediatek,mt7622-pinctrl" for MT7622 SoC
+ - reg: offset and length of the pinctrl space
+
+ - gpio-controller: Marks the device node as a GPIO controller.
+ - #gpio-cells: Should be two. The first cell is the pin number and the
+ second is the GPIO flags.
+
+Optional properties:
+- interrupt-controller : Marks the device node as an interrupt controller
+
+If the property interrupt-controller is defined, following property is required
+- reg-names: A string describing the "reg" entries. Must contain "eint".
+- interrupts : The interrupt output from the controller.
+- #interrupt-cells: Should be two.
+
+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".
+
+MT7622 pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, slew rate, etc.
+
+We support 2 types of configuration nodes. Those nodes can be either pinmux
+nodes or pinconf nodes. Each configuration node can consist of multiple nodes
+describing the pinmux and pinconf options.
+
+The name of each subnode doesn't matter as long as it is unique; all subnodes
+should be enumerated and processed purely based on their content.
+
+== pinmux nodes content ==
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pinmux subnode:
+
+Required properties are:
+ - groups: An array of strings. Each string contains the name of a group.
+ Valid values for these names are listed below.
+ - function: A string containing the name of the function to mux to the
+ group. Valid values for function names are listed below.
+
+== pinconf nodes content ==
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pinconf subnode:
+
+Required properties are:
+ - pins: An array of strings. Each string contains the name of a pin.
+ Valid values for these names are listed below.
+ - groups: An array of strings. Each string contains the name of a group.
+ Valid values for these names are listed below.
+
+Optional properies are:
+ bias-disable, bias-pull, bias-pull-down, input-enable,
+ input-schmitt-enable, input-schmitt-disable, output-enable
+ output-low, output-high, drive-strength, slew-rate
+
+ Valid arguments for 'slew-rate' are '0' for no slew rate controlled and '1' for
+ slower slew rate respectively.
+ Valid arguments for 'drive-strength', 4, 8, 12, or 16 in mA.
+
+The following specific properties as defined are valid to specify in a pinconf
+subnode:
+
+Optional properties are:
+ - mediatek,tdsel: An integer describing the steps for output level shifter duty
+ cycle when asserted (high pulse width adjustment). Valid arguments are from 0
+ to 15.
+ - mediatek,rdsel: An integer describing the steps for input level shifter duty
+ cycle when asserted (high pulse width adjustment). Valid arguments are from 0
+ to 63.
+
+== Valid values for pins, function and groups on MT7622 ==
+
+Valid values for pins are:
+pins can be referenced via the pin names as the below table shown and the
+related physical number is also put ahead of those names which helps cross
+references to pins between groups to know whether pins assignment conflict
+happens among devices try to acquire those available pins.

+Palmas Pincontrol bindings
+
+The pins of Palmas device can be set on different option and provides
+the configuration for Pull UP/DOWN, open drain etc.
+
+Required properties:
+- compatible: It must be one of following:
+ - "ti,palmas-pinctrl" for Palma series of the pincontrol.
+ - "ti,tps65913-pinctrl" for Palma series device TPS65913.
+ - "ti,tps80036-pinctrl" for Palma series device TPS80036.
+
+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".
+
+Palmas's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+list of pins. This configuration can include the mux function to select on
+those pin(s), and various pin configuration parameters, such as pull-up,
+open drain.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+Optional properties:
+- ti,palmas-enable-dvfs1: Enable DVFS1. Configure pins for DVFS1 mode.
+ Selection primary or secondary function associated to I2C2_SCL_SCE,
+ I2C2_SDA_SDO pin/pad for DVFS1 interface
+- ti,palmas-enable-dvfs2: Enable DVFS2. Configure pins for DVFS2 mode.
+ Selection primary or secondary function associated to GPADC_START
+ and SYSEN2 pin/pad for DVFS2 interface
+- ti,palmas-override-powerhold: This is applicable for PMICs for which
+ GPIO7 is configured in POWERHOLD mode which has higher priority
+ over DEV_ON bit and keeps the PMIC supplies on even after the DEV_ON
+ bit is turned off. This property enables driver to over ride the
+ POWERHOLD value to GPIO7 so as to turn off the PMIC in power off
+ scenarios. So for GPIO7 if ti,palmas-override-powerhold is set
+ then the GPIO_7 field should never be muxed to anything else.
+ It should be set to POWERHOLD by default and only in case of
+ power off scenarios the driver will over ride the mux value.
+
+This binding uses the following generic properties as defined in
+pinctrl-bindings.txt:
+
+Required: pins
+Options: function, bias-disable, bias-pull-up, bias-pull-down,
+ drive-open-drain.
+
+Note that many of these properties are only valid for certain specific pins.
+See the Palmas device datasheet for complete details regarding which pins
+support which functionality.
+
+Valid values for pin names are:
+ gpio0, gpio1, gpio2, gpio3, gpio4, gpio5, gpio6, gpio7, gpio8, gpio9,
+ gpio10, gpio11, gpio12, gpio13, gpio14, gpio15, vac, powergood,
+ nreswarm, pwrdown, gpadc_start, reset_in, nsleep, enable1, enable2,
+ int.
+
+Valid value of function names are:
+ gpio, led, pwm, regen, sysen, clk32kgaudio, id, vbus_det, chrg_det,
+ vac, vacok, powergood, usb_psel, msecure, pwrhold, int, nreswarm,
+ simrsto, simrsti, low_vbat, wireless_chrg1, rcm, pwrdown, gpadc_start,
+ reset_in, nsleep, enable.
+
+There are 4 special functions: opt0, opt1, opt2 and opt3. If any of these
+functions is selected then directly pins register will be written with 0, 1, 2
+or 3 respectively if it is valid for that pins or list of pins.
+
+Example:
+ palmas: tps65913 {
+ ....
+ pinctrl {
+ compatible = "ti,tps65913-pinctrl";
+ ti,palmas-enable-dvfs1;
+ pinctrl-names = "default";

+
+This driver assumes that there is only one register for each pin (unless the

+
+The pin configuration nodes for pinctrl-single are specified as pinctrl

+
+ pinctrl-single,pins = <0xdc 0x118>;
+
+Where 0xdc is the offset from the pinctrl register base address for the
+device pinctrl register, and 0x118 contains the desired value of the

+
+Where 0xdc is the offset from the pinctrl register base address for the
+device pinctrl register, 0x18 is the desired value, and 0xff is the sub mask to

+*ST pin controller.
+
+Each multi-function pin is controlled, driven and routed through the
+PIO multiplexing block. Each pin supports GPIO functionality (ALT0)
+and multiple alternate functions(ALT1 - ALTx) that directly connect
+the pin to different hardware blocks.
+
+When a pin is in GPIO mode, Output Enable (OE), Open Drain(OD), and
+Pull Up (PU) are driven by the related PIO block.
+
+ST pinctrl driver controls PIO multiplexing block and also interacts with
+gpio driver to configure a pin.
+
+GPIO bank can have one of the two possible types of interrupt-wirings.
+
+First type is via irqmux, single interrupt is used by multiple gpio banks. This
+reduces number of overall interrupts numbers required. All these banks belong to
+a single pincontroller.
+ _________
+ | |----> [gpio-bank (n) ]
+ | |----> [gpio-bank (n + 1)]
+ [irqN]-- | irq-mux |----> [gpio-bank (n + 2)]
+ | |----> [gpio-bank (... )]
+ |_________|----> [gpio-bank (n + 7)]
+
+Second type has a dedicated interrupt per gpio bank.
+
+ [irqN]----> [gpio-bank (n)]
+
+
+Pin controller node:
+Required properties:
+- compatible : should be "st,stih407-<pio-block>-pinctrl"

+
+Required properties:

+
+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".
+
+Each pin configuration node lists the pin(s) to which it applies, and one or
+more of the mux functions to select on those pin(s), and pull-up/down
+configuration. Each subnode only affects those parameters that are explicitly
+listed. In other words, a subnode that lists only a mux function implies no
+information about any pull configuration. Similarly, a subnode that lists only
+a pull parameter implies no information about the mux function.
+
+Required subnode-properties:
+- wm,pins: An array of cells. Each cell contains the ID of a pin.
+
+Optional subnode-properties:
+- wm,function: Integer, containing the function to mux to the pin(s):
+ 0: GPIO in
+ 1: GPIO out
+ 2: alternate
+
+- wm,pull: Integer, representing the pull-down/up to apply to the pin(s):
+ 0: none
+ 1: down
+ 2: up
+
+Each of wm,function and wm,pull may contain either a single value which
+will be applied to all pins in wm,pins, or one value for each entry in
+wm,pins.

+* ZTE ZX Pin Controller
+
+The pin controller on ZTE ZX platforms is kinda of hybrid. It consists of
+a main controller and an auxiliary one. For example, on ZX296718 SoC, the
+main controller is TOP_PMM and the auxiliary one is AON_IOCFG. Both
+controllers work together to control pin multiplexing and configuration in
+the way illustrated as below.
+
+
+ GMII_RXD3 ---+
+ |
+ DVI1_HS ---+----------------------------- GMII_RXD3 (TOP pin)
+ |
+ BGPIO16 ---+ ^
+ | pinconf
+ ^ |
+ | pinmux |
+ | |
+
+ TOP_PMM (main) AON_IOCFG (aux)
+
+ | | |
+ | pinmux | |
+ | pinmux v |
+ v | pinconf
+ KEY_ROW2 ---+ v
+ PORT1_LCD_TE ---+ |
+ | AGPIO10 ---+------ KEY_ROW2 (AON pin)
+ I2S0_DOUT3 ---+ |
+ |-----------------------+
+ PWM_OUT3 ---+
+ |
+ VGA_VS1 ---+
+
+
+For most of pins like GMII_RXD3 in the figure, the pinmux function is
+controlled by TOP_PMM block only, and this type of pins are meant by term
+'TOP pins'. For pins like KEY_ROW2, the pinmux is controlled by both
+TOP_PMM and AON_IOCFG blocks, as the available multiplexing functions for
+the pin spread in both controllers. This type of pins are called 'AON pins'.
+Though pinmux implementation is quite different, pinconf is same for both
+types of pins. Both are controlled by auxiliary controller, i.e. AON_IOCFG
+on ZX296718.
+
+Required properties:
+- compatible: should be "zte,zx296718-pmm".
+- reg: the register physical address and length.
+- zte,auxiliary-controller: phandle to the auxiliary pin controller which
+ implements pinmux for AON pins and pinconf for all pins.
+
+The following pin configuration are supported. Please refer to
+pinctrl-bindings.txt in this directory for more details of the common
+pinctrl bindings used by client devices.
+
+- bias-pull-up
+- bias-pull-down
+- drive-strength
+- input-enable
+- slew-rate
+
+Examples:
+
+iocfg: pin-controller@119000 {
+ compatible = "zte,zx296718-iocfg";
+ reg = <0x119000 0x1000>;

+phrase "pin configuration node".
+
+Qualcomm's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength,
+ output-low, output-high.
+
+Non-empty subnodes must specify the 'pins' property.
+
+Valid values for pins are:
+ gpio0-gpio89
+
+Valid values for function are:
+ cam_mclk, codec_mic_i2s, codec_spkr_i2s, gp_clk_0a, gp_clk_0b, gp_clk_1a,
+ gp_clk_1b, gp_clk_2a, gp_clk_2b, gpio, gsbi1, gsbi2, gsbi3, gsbi4,
+ gsbi4_cam_i2c, gsbi5, gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6,

+- interrupts: Should be the parent IRQ of the TLMM block.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two.
+ The first cell is the gpio pin number and the
+ second cell is used for optional parameters.
+- gpio-ranges: see ../gpio/gpio.txt
+
+Optional properties:
+
+- gpio-reserved-ranges: see ../gpio/gpio.txt
+
+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+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".
+
+Qualcomm's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength.
+
+Non-empty subnodes must specify the 'pins' property.
+Note that not all properties are valid for all pins.
+
+
+Valid values for pins are:
+ gpio0-gpio145
+ Supports mux, bias and drive-strength
+
+ sdc1_clk, sdc1_cmd, sdc1_data, sdc2_clk, sdc2_cmd, sdc2_data
+ Supports bias and drive-strength
+
+ hsic_data, hsic_strobe
+ Supports only mux
+
+Valid values for function are:

+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a

+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated

+
+Each subnode only affects those parameters that are explicitly listed. In

+
+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".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.

+* Renesas Pin Function Controller (GPIO and Pin Mux/Config)
+
+The Pin Function Controller (PFC) is a Pin Mux/Config controller. On SH73A0,
+R8A73A4 and R8A7740 it also acts as a GPIO controller.
+
+
+Pin Control
+-----------
+
+Required Properties:
+
+ - compatible: should be one of the following.
+ - "renesas,pfc-emev2": for EMEV2 (EMMA Mobile EV2) compatible pin-controller.
+ - "renesas,pfc-r8a73a4": for R8A73A4 (R-Mobile APE6) compatible pin-controller.
+ - "renesas,pfc-r8a7740": for R8A7740 (R-Mobile A1) compatible pin-controller.
+ - "renesas,pfc-r8a7743": for R8A7743 (RZ/G1M) compatible pin-controller.
+ - "renesas,pfc-r8a7745": for R8A7745 (RZ/G1E) compatible pin-controller.
+ - "renesas,pfc-r8a77470": for R8A77470 (RZ/G1C) compatible pin-controller.
+ - "renesas,pfc-r8a7778": for R8A7778 (R-Car M1) compatible pin-controller.
+ - "renesas,pfc-r8a7779": for R8A7779 (R-Car H1) compatible pin-controller.
+ - "renesas,pfc-r8a7790": for R8A7790 (R-Car H2) compatible pin-controller.
+ - "renesas,pfc-r8a7791": for R8A7791 (R-Car M2-W) compatible pin-controller.
+ - "renesas,pfc-r8a7792": for R8A7792 (R-Car V2H) compatible pin-controller.
+ - "renesas,pfc-r8a7793": for R8A7793 (R-Car M2-N) compatible pin-controller.
+ - "renesas,pfc-r8a7794": for R8A7794 (R-Car E2) compatible pin-controller.
+ - "renesas,pfc-r8a7795": for R8A7795 (R-Car H3) compatible pin-controller.

+ - "renesas,pfc-r8a77995": for R8A77995 (R-Car D3) compatible pin-controller.
+ - "renesas,pfc-sh73a0": for SH73A0 (SH-Mobile AG5) compatible pin-controller.
+
+ - reg: Base address and length of each memory resource used by the pin
+ controller hardware module.
+
+Optional properties:
+
+ - #gpio-range-cells: Mandatory when the PFC doesn't handle GPIO, forbidden
+ otherwise. Should be 3.
+
+ - interrupts-extended: Specify the interrupts associated with external
+ IRQ pins. This property is mandatory when the PFC handles GPIOs and
+ forbidden otherwise. When specified, it must contain one interrupt per
+ external IRQ, sorted by external IRQ number.
+
+The PFC node also acts as a container for pin configuration nodes. Please refer
+to pinctrl-bindings.txt in this directory for the definition of the term "pin
+configuration node" and for the common pinctrl bindings used by client devices.
+
+Each pin configuration node represents a desired configuration for a pin, a
+pin group, or a list of pins or pin groups. The configuration can include the
+function to select on those pin(s) and pin configuration parameters (such as
+pull-up and pull-down).
+
+Pin configuration nodes contain pin configuration properties, either directly
+or grouped in child subnodes. Both pin muxing and configuration parameters can
+be grouped in that way and referenced as a single pin configuration node by
+client devices.
+
+A configuration node or subnode must reference at least one pin (through the
+pins or pin groups properties) and contain at least a function or one
+configuration parameter. When the function is present only pin groups can be
+used to reference pins.
+
+All pin configuration nodes and subnodes names are ignored. All of those nodes
+are parsed through phandles and processed purely based on their content.
+
+Pin Configuration Node Properties:
+
+- pins : An array of strings, each string containing the name of a pin.
+- groups : An array of strings, each string containing the name of a pin
+ group.
+
+- function: A string containing the name of the function to mux to the pin
+ group(s) specified by the groups property.
+
+ Valid values for pin, group and function names can be found in the group and
+ function arrays of the PFC data file corresponding to the SoC
+ (drivers/pinctrl/sh-pfc/pfc-*.c)
+
+The pin configuration parameters use the generic pinconf bindings defined in
+pinctrl-bindings.txt in this directory. The supported parameters are
+bias-disable, bias-pull-up, bias-pull-down, drive-strength and power-source. For
+pins that have a configurable I/O voltage, the power-source value should be the
+nominal I/O voltage in millivolts.
+
+
+GPIO
+----
+
+On SH73A0, R8A73A4 and R8A7740 the PFC node is also a GPIO controller node.
+
+Required Properties:
+
+ - gpio-controller: Marks the device node as a gpio controller.
+
+ - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
+ cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
+ GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
+
+The syntax of the gpio specifier used by client nodes should be the following
+with values derived from the SoC user manual.
+
+ <[phandle of the gpio controller node]
+ [pin number within the gpio controller]
+ [flags]>
+
+On other mach-shmobile platforms GPIO is handled by the gpio-rcar driver.
+Please refer to Documentation/devicetree/bindings/gpio/renesas,gpio-rcar.txt
+for documentation of the GPIO device tree bindings on those platforms.

+Renesas RZ/A1 combined Pin and GPIO controller
+
+The Renesas SoCs of the RZ/A1 family feature a combined Pin and GPIO controller,
+named "Ports" in the hardware reference manual.
+Pin multiplexing and GPIO configuration is performed on a per-pin basis
+writing configuration values to per-port register sets.
+Each "port" features up to 16 pins, each of them configurable for GPIO
+function (port mode) or in alternate function mode.
+Up to 8 different alternate function modes exist for each single pin.
+
+Pin controller node
+-------------------
+
+Required properties:
+ - compatible: should be:
+ - "renesas,r7s72100-ports": for RZ/A1H
+ - "renesas,r7s72101-ports", "renesas,r7s72100-ports": for RZ/A1M
+ - "renesas,r7s72102-ports": for RZ/A1L
+
+ - reg
+ address base and length of the memory area where the pin controller
+ hardware is mapped to.
+
+Example:
+Pin controller node for RZ/A1H SoC (r7s72100)
+
+pinctrl: pin-controller@fcfe3000 {
+ compatible = "renesas,r7s72100-ports";
+
+ reg = <0xfcfe3000 0x4230>;
+};
+
+Sub-nodes
+---------
+
+The child nodes of the pin controller node describe a pin multiplexing
+function or a GPIO controller alternatively.
+
+- Pin multiplexing sub-nodes:
+ A pin multiplexing sub-node describes how to configure a set of
+ (or a single) pin in some desired alternate function mode.
+ A single sub-node may define several pin configurations.
+ A few alternate function require special pin configuration flags to be
+ supplied along with the alternate function configuration number.
+ The hardware reference manual specifies when a pin function requires
+ "software IO driven" mode to be specified. To do so use the generic
+ properties from the <include/linux/pinctrl/pinconf_generic.h> header file
+ to instruct the pin controller to perform the desired pin configuration
+ operation.
+ Please refer to pinctrl-bindings.txt to get to know more on generic
+ pin properties usage.
+
+ The allowed generic formats for a pin multiplexing sub-node are the
+ following ones:
+
+ node-1 {
+ pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+ GENERIC_PINCONFIG;
+ };
+
+ node-2 {
+ sub-node-1 {
+ pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+ GENERIC_PINCONFIG;
+ };
+
+ sub-node-2 {
+ pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+ GENERIC_PINCONFIG;
+ };
+
+ ...
+
+ sub-node-n {
+ pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+ GENERIC_PINCONFIG;
+ };
+ };
+
+ Use the second format when pins part of the same logical group need to have
+ different generic pin configuration flags applied.
+
+ Client sub-nodes shall refer to pin multiplexing sub-nodes using the phandle
+ of the most external one.
+
+ Eg.
+
+ client-1 {
+ ...
+ pinctrl-0 = <&node-1>;
+ ...
+ };
+
+ client-2 {
+ ...
+ pinctrl-0 = <&node-2>;
+ ...
+ };
+
+ Required properties:
+ - pinmux:
+ integer array representing pin number and pin multiplexing configuration.
+ When a pin has to be configured in alternate function mode, use this
+ property to identify the pin by its global index, and provide its
+ alternate function configuration number along with it.
+ When multiple pins are required to be configured as part of the same
+ alternate function they shall be specified as members of the same
+ argument list of a single "pinmux" property.
+ Helper macros to ease assembling the pin index from its position
+ (port where it sits on and pin number) and alternate function identifier
+ are provided by the pin controller header file at:
+ <include/dt-bindings/pinctrl/r7s72100-pinctrl.h>
+ Integers values in "pinmux" argument list are assembled as:
+ ((PORT * 16 + PIN) | MUX_FUNC << 16)
+
+ Optional generic properties:
+ - input-enable:
+ enable input bufer for pins requiring software driven IO input
+ operations.
+ - output-high:
+ enable output buffer for pins requiring software driven IO output
+ operations. output-low can be used alternatively, as line value is
+ ignored by the driver.
+
+ The hardware reference manual specifies when a pin has to be configured to
+ work in bi-directional mode and when the IO direction has to be specified
+ by software. Bi-directional pins are managed by the pin controller driver
+ internally, while software driven IO direction has to be explicitly
+ selected when multiple options are available.
+
+ Example:
+ A serial communication interface with a TX output pin and an RX input pin.
+
+ &pinctrl {
+ scif2_pins: serial2 {
+ pinmux = <RZA1_PINMUX(3, 0, 6)>, <RZA1_PINMUX(3, 2, 4)>;
+ };
+ };
+
+ Pin #0 on port #3 is configured as alternate function #6.
+ Pin #2 on port #3 is configured as alternate function #4.
+
+ Example 2:
+ I2c master: both SDA and SCL pins need bi-directional operations
+
+ &pinctrl {
+ i2c2_pins: i2c2 {
+ pinmux = <RZA1_PINMUX(1, 4, 1)>, <RZA1_PINMUX(1, 5, 1)>;
+ };
+ };
+
+ Pin #4 on port #1 is configured as alternate function #1.
+ Pin #5 on port #1 is configured as alternate function #1.
+ Both need to work in bi-directional mode, the driver manages this internally.
+
+ Example 3:
+ Multi-function timer input and output compare pins.
+ Configure TIOC0A as software driven input and TIOC0B as software driven
+ output.
+
+ &pinctrl {
+ tioc0_pins: tioc0 {
+ tioc0_input_pins {
+ pinumx = <RZA1_PINMUX(4, 0, 2)>;
+ input-enable;
+ };
+
+ tioc0_output_pins {
+ pinmux = <RZA1_PINMUX(4, 1, 1)>;
+ output-enable;
+ };
+ };
+ };
+
+ &tioc0 {
+ ...
+ pinctrl-0 = <&tioc0_pins>;
+ ...
+ };
+
+ Pin #0 on port #4 is configured as alternate function #2 with IO direction
+ specified by software as input.
+ Pin #1 on port #4 is configured as alternate function #1 with IO direction
+ specified by software as output.
+
+- GPIO controller sub-nodes:
+ Each port of the r7s72100 pin controller hardware is itself a GPIO controller.
+ Different SoCs have different numbers of available pins per port, but
+ generally speaking, each of them can be configured in GPIO ("port") mode
+ on this hardware.
+ Describe GPIO controllers using sub-nodes with the following properties.
+
+ Required properties:
+ - gpio-controller
+ empty property as defined by the GPIO bindings documentation.
+ - #gpio-cells
+ number of cells required to identify and configure a GPIO.
+ Shall be 2.
+ - gpio-ranges
+ Describes a GPIO controller specifying its specific pin base, the pin
+ base in the global pin numbering space, and the number of controlled
+ pins, as defined by the GPIO bindings documentation. Refer to
+ Documentation/devicetree/bindings/gpio/gpio.txt file for a more detailed
+ description.
+
+ Example:
+ A GPIO controller node, controlling 16 pins indexed from 0.
+ The GPIO controller base in the global pin indexing space is pin 48, thus
+ pins [0 - 15] on this controller map to pins [48 - 63] in the global pin
+ indexing space.
+
+ port3: gpio-3 {
+ gpio-controller;
+ #gpio-cells = <2>;
+ gpio-ranges = <&pinctrl 0 48 16>;
+ };
+
+ A device node willing to use pins controlled by this GPIO controller, shall
+ refer to it as follows:
+
+ led1 {
+ gpios = <&port3 10 GPIO_ACTIVE_LOW>;
+ };

+* Rockchip Pinmux Controller
+
+The Rockchip Pinmux Controller, 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 several
+muxing options with option 0 being the use as a GPIO.
+
+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".
+
+The Rockchip 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, etc.
+
+The pins are grouped into up to 5 individual pin banks which need to be
+defined as gpio sub-nodes of the pinmux controller.
+
+Required properties for iomux controller:
+ - compatible: should be
+ "rockchip,px30-pinctrl": for Rockchip PX30
+ "rockchip,rv1108-pinctrl": for Rockchip RV1108
+ "rockchip,rk2928-pinctrl": for Rockchip RK2928

+ "rockchip,rk3368-pinctrl": for Rockchip RK3368
+ "rockchip,rk3399-pinctrl": for Rockchip RK3399
+
+ - rockchip,grf: phandle referencing a syscon providing the
+ "general register files"
+
+Optional properties for iomux controller:
+ - rockchip,pmu: phandle referencing a syscon providing the pmu registers
+ as some SoCs carry parts of the iomux controller registers there.
+ Required for at least rk3188 and rk3288. On the rk3368 this should
+ point to the PMUGRF syscon.
+
+Deprecated properties for iomux controller:
+ - reg: first element is the general register space of the iomux controller
+ It should be large enough to contain also separate pull registers.
+ second element is the separate pull register space of the rk3188.
+ Use rockchip,grf and rockchip,pmu described above instead.
+
+Required properties for gpio sub nodes:
+ - compatible: "rockchip,gpio-bank"
+ - reg: register of the gpio bank (different than the iomux registerset)
+ - interrupts: base interrupt of the gpio bank in the interrupt controller
+ - clocks: clock that drives this bank
+ - gpio-controller: identifies the node as a gpio controller and pin bank.
+ - #gpio-cells: number of cells in GPIO specifier. Since the generic GPIO
+ binding is used, the amount of cells must be specified as 2. See generic
+ GPIO binding documentation for description of particular cells.
+ - interrupt-controller: identifies the controller node as interrupt-parent.
+ - #interrupt-cells: the value of this property should be 2 and the interrupt
+ cells should use the standard two-cell scheme described in
+ bindings/interrupt-controller/interrupts.txt
+
+Deprecated properties for gpio sub nodes:
+ - compatible: "rockchip,rk3188-gpio-bank0"
+ - reg: second element: separate pull register for rk3188 bank0, use
+ rockchip,pmu described above instead
+
+Required properties for pin configuration node:
+ - rockchip,pins: 3 integers array, represents a group of pins mux and config
+ setting. The format is rockchip,pins = <PIN_BANK PIN_BANK_IDX MUX &phandle>.
+ The MUX 0 means gpio and MUX 1 to N mean the specific device function.
+ The phandle of a node containing the generic pinconfig options
+ to use, as described in pinctrl-bindings.txt in this directory.

+Samsung GPIO and Pin Mux/Config controller
+
+Samsung's ARM based SoC's integrates a GPIO and Pin mux/config hardware
+controller. It controls the input/output settings on the available pads/pins
+and also provides ability to multiplex and configure the output of various
+on-chip controllers onto these pads.
+
+Required Properties:
+- compatible: should be one of the following.
+ - "samsung,s3c2412-pinctrl": for S3C2412-compatible pin-controller,
+ - "samsung,s3c2416-pinctrl": for S3C2416-compatible pin-controller,
+ - "samsung,s3c2440-pinctrl": for S3C2440-compatible pin-controller,
+ - "samsung,s3c2450-pinctrl": for S3C2450-compatible pin-controller,
+ - "samsung,s3c64xx-pinctrl": for S3C64xx-compatible pin-controller,
+ - "samsung,s5pv210-pinctrl": for S5PV210-compatible pin-controller,
+ - "samsung,exynos3250-pinctrl": for Exynos3250 compatible pin-controller.
+ - "samsung,exynos4210-pinctrl": for Exynos4210 compatible pin-controller.
+ - "samsung,exynos4x12-pinctrl": for Exynos4x12 compatible pin-controller.
+ - "samsung,exynos5250-pinctrl": for Exynos5250 compatible pin-controller.
+ - "samsung,exynos5260-pinctrl": for Exynos5260 compatible pin-controller.
+ - "samsung,exynos5410-pinctrl": for Exynos5410 compatible pin-controller.
+ - "samsung,exynos5420-pinctrl": for Exynos5420 compatible pin-controller.
+ - "samsung,exynos5433-pinctrl": for Exynos5433 compatible pin-controller.
+ - "samsung,exynos7-pinctrl": for Exynos7 compatible pin-controller.
+
+- reg: Base address of the pin controller hardware module and length of
+ the address space it occupies.
+
+ - reg: Second base address of the pin controller if the specific registers
+ of the pin controller are separated into the different base address.
+
+ Eg: GPF[1-5] of Exynos5433 are separated into the two base address.
+ - First base address is for GPAx and GPF[1-5] external interrupt
+ registers.
+ - Second base address is for GPF[1-5] pinctrl registers.
+
+ pinctrl_0: pinctrl@10580000 {
+ compatible = "samsung,exynos5433-pinctrl";
+ reg = <0x10580000 0x1a20>, <0x11090000 0x100>;
+
+ wakeup-interrupt-controller {
+ compatible = "samsung,exynos7-wakeup-eint";
+ interrupts = <0 16 0>;
+ };
+ };
+
+- Pin banks as child nodes: Pin banks of the controller are represented by child
+ nodes of the controller node. Bank name is taken from name of the node. Each
+ bank node must contain following properties:
+
+ - gpio-controller: identifies the node as a gpio controller and pin bank.
+ - #gpio-cells: number of cells in GPIO specifier. Since the generic GPIO
+ binding is used, the amount of cells must be specified as 2. See the below
+ mentioned gpio binding representation for description of particular cells.
+
+ Eg: <&gpx2 6 0>
+ <[phandle of the gpio controller node]
+ [pin number within the gpio controller]
+ [flags]>
+
+ Values for gpio specifier:
+ - Pin number: is a value between 0 to 7.
+ - Flags: 0 - Active High
+ 1 - Active Low
+
+- Pin mux/config groups as child nodes: The pin mux (selecting pin function
+ mode) and pin config (pull up/down, driver strength) settings are represented
+ as child nodes of the pin-controller node. There should be atleast one
+ child node and there is no limit on the count of these child nodes. It is
+ also possible for a child node to consist of several further child nodes
+ to allow grouping multiple pinctrl groups into one. The format of second
+ level child nodes is exactly the same as for first level ones and is
+ described below.
+
+ The child node should contain a list of pin(s) on which a particular pin
+ function selection or pin configuration (or both) have to applied. This
+ list of pins is specified using the property name "samsung,pins". There
+ should be atleast one pin specfied for this property and there is no upper
+ limit on the count of pins that can be specified. The pins are specified
+ using pin names which are derived from the hardware manual of the SoC. As
+ an example, the pins in GPA0 bank of the pin controller can be represented
+ as "gpa0-0", "gpa0-1", "gpa0-2" and so on. The names should be in lower case.
+ The format of the pin names should be (as per the hardware manual)
+ "[pin bank name]-[pin number within the bank]".
+
+ The pin function selection that should be applied on the pins listed in the
+ child node is specified using the "samsung,pin-function" property. The value
+ of this property that should be applied to each of the pins listed in the
+ "samsung,pins" property should be picked from the hardware manual of the SoC
+ for the specified pin group. This property is optional in the child node if
+ no specific function selection is desired for the pins listed in the child
+ node. The value of this property is used as-is to program the pin-controller
+ function selector register of the pin-bank.
+
+ The child node can also optionally specify one or more of the pin
+ configuration that should be applied on all the pins listed in the
+ "samsung,pins" property of the child node. The following pin configuration
+ properties are supported.
+
+ - samsung,pin-val: Initial value of pin output buffer.
+ - samsung,pin-pud: Pull up/down configuration.
+ - samsung,pin-drv: Drive strength configuration.
+ - samsung,pin-pud-pdn: Pull up/down configuration in power down mode.
+ - samsung,pin-drv-pdn: Drive strength configuration in power down mode.
+
+ The values specified by these config properties should be derived from the
+ hardware manual and these values are programmed as-is into the pin
+ pull up/down and driver strength register of the pin-controller.
+
+ Note: A child should include atleast a pin function selection property or
+ pin configuration property (one or more) or both.
+
+ The client nodes that require a particular pin function selection and/or
+ pin configuration should use the bindings listed in the "pinctrl-bindings.txt"
+ file.
+
+External GPIO and Wakeup Interrupts:
+
+The controller supports two types of external interrupts over gpio. The first
+is the external gpio interrupt and second is the external wakeup interrupts.
+The difference between the two is that the external wakeup interrupts can be
+used as system wakeup events.
+
+A. External GPIO Interrupts: For supporting external gpio interrupts, the
+ following properties should be specified in the pin-controller device node.
+
+ - interrupts: interrupt specifier for the controller. The format and value of
+ the interrupt specifier depends on the interrupt parent for the controller.
+
+ In addition, following properties must be present in node of every bank
+ of pins supporting GPIO interrupts:
+
+ - interrupt-controller: identifies the controller node as interrupt-parent.
+ - #interrupt-cells: the value of this property should be 2.
+ - First Cell: represents the external gpio interrupt number local to the
+ external gpio interrupt space of the controller.
+ - Second Cell: flags to identify the type of the interrupt
+ - 1 = rising edge triggered
+ - 2 = falling edge triggered
+ - 3 = rising and falling edge triggered
+ - 4 = high level triggered
+ - 8 = low level triggered
+
+B. External Wakeup Interrupts: For supporting external wakeup interrupts, a
+ child node representing the external wakeup interrupt controller should be
+ included in the pin-controller device node.
+
+ Only one pin-controller device node can include external wakeup interrupts
+ child node (in other words, only one External Wakeup Interrupts
+ pin-controller is supported).
+
+ This child node should include following properties:
+
+ - compatible: identifies the type of the external wakeup interrupt controller
+ The possible values are:
+ - samsung,s3c2410-wakeup-eint: represents wakeup interrupt controller
+ found on Samsung S3C24xx SoCs except S3C2412 and S3C2413,
+ - samsung,s3c2412-wakeup-eint: represents wakeup interrupt controller
+ found on Samsung S3C2412 and S3C2413 SoCs,
+ - samsung,s3c64xx-wakeup-eint: represents wakeup interrupt controller
+ found on Samsung S3C64xx SoCs,
+ - samsung,s5pv210-wakeup-eint: represents wakeup interrupt controller
+ found on Samsung S5Pv210 SoCs,
+ - samsung,exynos4210-wakeup-eint: represents wakeup interrupt controller
+ found on Samsung Exynos4210 and S5PC110/S5PV210 SoCs.
+ - samsung,exynos7-wakeup-eint: represents wakeup interrupt controller
+ found on Samsung Exynos7 SoC.
+ - interrupts: interrupt used by multiplexed wakeup interrupts.
+
+ In addition, following properties must be present in node of every bank
+ of pins supporting wake-up interrupts:
+
+ - interrupt-controller: identifies the node as interrupt-parent.
+ - #interrupt-cells: the value of this property should be 2
+ - First Cell: represents the external wakeup interrupt number local to
+ the external wakeup interrupt space of the controller.
+ - Second Cell: flags to identify the type of the interrupt
+ - 1 = rising edge triggered
+ - 2 = falling edge triggered
+ - 3 = rising and falling edge triggered
+ - 4 = high level triggered
+ - 8 = low level triggered
+
+ Node of every bank of pins supporting direct wake-up interrupts (without
+ multiplexing) must contain following properties:
+
+ - interrupts: interrupts of the interrupt parent which are used for external
+ wakeup interrupts from pins of the bank, must contain interrupts for all
+ pins of the bank.
+
+Aliases:
+
+All the pin controller nodes should be represented in the aliases node using
+the following format 'pinctrl{n}' where n is a unique number for the alias.
+
+Aliases for controllers compatible with "samsung,exynos7-pinctrl":
+- pinctrl0: pin controller of ALIVE block,
+- pinctrl1: pin controller of BUS0 block,
+- pinctrl2: pin controller of NFC block,
+- pinctrl3: pin controller of TOUCH block,
+- pinctrl4: pin controller of FF block,
+- pinctrl5: pin controller of ESE block,
+- pinctrl6: pin controller of FSYS0 block,
+- pinctrl7: pin controller of FSYS1 block,
+- pinctrl8: pin controller of BUS1 block,
+- pinctrl9: pin controller of AUDIO block,

+* Spreadtrum Pin Controller
+
+The Spreadtrum pin controller are organized in 3 blocks (types).
+
+The first block comprises some global control registers, and each
+register contains several bit fields with one bit or several bits
+to configure for some global common configuration, such as domain
+pad driving level, system control select and so on ("domain pad
+driving level": One pin can output 3.0v or 1.8v, depending on the
+related domain pad driving selection, if the related domain pad
+slect 3.0v, then the pin can output 3.0v. "system control" is used
+to choose one function (like: UART0) for which system, since we
+have several systems (AP/CP/CM4) on one SoC.).
+
+There are too much various configuration that we can not list all
+of them, so we can not make every Spreadtrum-special configuration
+as one generic configuration, and maybe it will add more strange
+global configuration in future. Then we add one "sprd,control" to
+set these various global control configuration, and we need use
+magic number for this property.
+
+Moreover we recognise every fields comprising one bit or several
+bits in one global control register as one pin, thus we should
+record every pin's bit offset, bit width and register offset to
+configure this field (pin).
+
+The second block comprises some common registers which have unified
+register definition, and each register described one pin is used
+to configure the pin sleep mode, function select and sleep related
+configuration.
+
+Now we have 4 systems for sleep mode on SC9860 SoC: AP system,
+PUBCP system, TGLDSP system and AGDSP system. And the pin sleep
+related configuration are:
+- input-enable
+- input-disable
+- output-high
+- output-low
+- bias-pull-up
+- bias-pull-down
+
+In some situation we need set the pin sleep mode and pin sleep related
+configuration, to set the pin sleep related configuration automatically
+by hardware when the system specified by sleep mode goes into deep
+sleep mode. For example, if we set the pin sleep mode as PUBCP_SLEEP
+and set the pin sleep related configuration as "input-enable", which
+means when PUBCP system goes into deep sleep mode, this pin will be set
+input enable automatically.
+
+Moreover we can not use the "sleep" state, since some systems (like:
+PUBCP system) do not run linux kernel OS (only AP system run linux
+kernel on SC9860 platform), then we can not select "sleep" state
+when the PUBCP system goes into deep sleep mode. Thus we introduce
+"sprd,sleep-mode" property to set pin sleep mode.
+
+The last block comprises some misc registers which also have unified
+register definition, and each register described one pin is used to
+configure drive strength, pull up/down and so on. Especially for pull
+up, we have two kind pull up resistor: 20K and 4.7K.
+
+Required properties for Spreadtrum pin controller:
+- compatible: "sprd,<soc>-pinctrl"

+* STM32 GPIO and Pin Mux/Config controller
+
+STMicroelectronics's STM32 MCUs intregrate a GPIO and Pin mux/config hardware
+controller. It controls the input/output settings on the available pins and
+also provides ability to multiplex and configure the output of various on-chip
+controllers onto these pads.
+
+Pin controller node:
+Required properies:
+ - compatible: value should be one of the following:
+ "st,stm32f429-pinctrl"
+ "st,stm32f469-pinctrl"
+ "st,stm32f746-pinctrl"
+ "st,stm32f769-pinctrl"
+ "st,stm32h743-pinctrl"
+ "st,stm32mp157-pinctrl"
+ "st,stm32mp157-z-pinctrl"
+ - #address-cells: The value of this property must be 1
+ - #size-cells : The value of this property must be 1
+ - ranges : defines mapping between pin controller node (parent) to
+ gpio-bank node (children).
+ - pins-are-numbered: Specify the subnodes are using numbered pinmux to
+ specify pins.
+
+GPIO controller/bank node:
+Required properties:
+ - gpio-controller : Indicates this device is a GPIO controller
+ - #gpio-cells : Should be two.
+ The first cell is the pin number
+ The second one is the polarity:
+ - 0 for active high
+ - 1 for active low
+ - reg : The gpio address range, relative to the pinctrl range
+ - clocks : clock that drives this bank
+ - st,bank-name : Should be a name string for this bank as specified in
+ the datasheet
+
+Optional properties:
+ - reset: : Reference to the reset controller
+ - st,syscfg: Should be phandle/offset/mask.
+ -The phandle to the syscon node which includes IRQ mux selection register.
+ -The offset of the IRQ mux selection register
+ -The field mask of IRQ mux, needed if different of 0xf.
+ - gpio-ranges: Define a dedicated mapping between a pin-controller and
+ a gpio controller. Format is <&phandle a b c> with:
+ -(phandle): phandle of pin-controller.
+ -(a): gpio base offset in range.
+ -(b): pin base offset in range.
+ -(c): gpio count in range
+ This entry has to be used either if there are holes inside a bank:
+ GPIOB0/B1/B2/B14/B15 (see example 2)
+ or if banks are not contiguous:
+ GPIOA/B/C/E...
+ NOTE: If "gpio-ranges" is used for a gpio controller, all gpio-controller
+ have to use a "gpio-ranges" entry.
+ More details in Documentation/devicetree/bindings/gpio/gpio.txt.
+ - st,bank-ioport: should correspond to the EXTI IOport selection (EXTI line
+ used to select GPIOs as interrupts).
+
+Example 1:
+#include <dt-bindings/pinctrl/stm32f429-pinfunc.h>
+...
+
+ pin-controller {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "st,stm32f429-pinctrl";

+ reg = <0x0 0x400>;
+ resets = <&reset_ahb1 0>;
+ st,bank-name = "GPIOA";
+ };
+ ...
+ pin-functions nodes follow...
+ };
+
+Example 2:
+#include <dt-bindings/pinctrl/stm32f429-pinfunc.h>
+...
+
+ pinctrl: pin-controller {

+ <&pinctrl 14 30 2>;
+ };
+
+
+ ...
+ pin-functions nodes follow...
+ };
+
+
+Contents of function subnode node:
+----------------------------------
+Subnode format
+A pinctrl node should contain at least one subnode representing the
+pinctrl group available on the machine. Each subnode will list the
+pins it needs, and how they should be configured, with regard to muxer
+configuration, pullups, drive, output high/low and output speed.
+
+ node {
+ pinmux = <PIN_NUMBER_PINMUX>;
+ GENERIC_PINCONFIG;
+ };
+
+Required properties:
+- pinmux: integer array, represents gpio pin number and mux setting.
+ Supported pin number and mux varies for different SoCs, and are defined in
+ dt-bindings/pinctrl/<soc>-pinfunc.h directly.
+ These defines are calculated as:
+ ((port * 16 + line) << 8) | function
+ With:
+ - port: The gpio port index (PA = 0, PB = 1, ..., PK = 11)
+ - line: The line offset within the port (PA0 = 0, PA1 = 1, ..., PA15 = 15)
+ - function: The function number, can be:
+ * 0 : GPIO
+ * 1 : Alternate Function 0
+ * 2 : Alternate Function 1
+ * 3 : Alternate Function 2
+ * ...
+ * 16 : Alternate Function 15
+ * 17 : Analog
+
+ To simplify the usage, macro is available to generate "pinmux" field.
+ This macro is available here:
+ - include/dt-bindings/pinctrl/stm32-pinfunc.h
+
+ Some examples of using macro:
+ /* GPIO A9 set as alernate function 2 */
+ ... {
+ pinmux = <STM32_PINMUX('A', 9, AF2)>;
+ };
+ /* GPIO A9 set as GPIO */
+ ... {
+ pinmux = <STM32_PINMUX('A', 9, GPIO)>;
+ };
+ /* GPIO A9 set as analog */
+ ... {
+ pinmux = <STM32_PINMUX('A', 9, ANALOG)>;
+ };
+
+Optional properties:
+- GENERIC_PINCONFIG: is the generic pinconfig options to use.
+ Available options are:
+ - bias-disable,
+ - bias-pull-down,
+ - bias-pull-up,
+ - drive-push-pull,
+ - drive-open-drain,
+ - output-low
+ - output-high
+ - slew-rate = <x>, with x being:
+ < 0 > : Low speed
+ < 1 > : Medium speed
+ < 2 > : Fast speed
+ < 3 > : High speed
+
+Example:
+
+pin-controller {
+...
+ usart1_pins_a: usart1@0 {
+ pins1 {
+ pinmux = <STM32_PINMUX('A', 9, AF7)>;
+ bias-disable;
+ drive-push-pull;
+ slew-rate = <0>;
+ };
+ pins2 {
+ pinmux = <STM32_PINMUX('A', 10, AF7)>;
+ bias-disable;
+ };
+ };
+};
+
+&usart1 {
+ pinctrl-0 = <&usart1_pins_a>;
+ pinctrl-names = "default";
+};

+ST Ericsson Nomadik pinmux controller
+
+Required properties:
+- compatible: "stericsson,db8500-pinctrl", "stericsson,db8540-pinctrl",
+ "stericsson,stn8815-pinctrl"
+- nomadik-gpio-chips: array of phandles to the corresponding GPIO chips
+ (these have the register ranges used by the pin controller).
+- prcm: phandle to the PRCMU managing the back end of this pin controller
+
+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".
+
+ST Ericsson's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as input, output, pull up, pull down...
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content. The subnodes use the generic
+pin multiplexing node layout from the standard pin control bindings
+(see pinctrl-bindings.txt):
+
+Required pin multiplexing subnode properties:
+- function: A string containing the name of the function to mux to the
+ pin or group.
+- groups : An array of strings. Each string contains the name of a pin
+ group that will be combined with the function to form a multiplexing
+ set-up.
+
+Required pin configuration subnode properties:
+- pins: A string array describing the pins affected by the configuration
+ in the node.
+- ste,config: Handle of pin configuration node
+ (e.g. ste,config = <&slpm_in_wkup_pdis>)
+

+* Pin configuration for TI DA850/OMAP-L138/AM18x
+
+These SoCs have a separate controller for setting bias (internal pullup/down).
+Bias can only be selected for groups rather than individual pins.
+
+Required Properties:
+
+ - compatible: Must be "ti,da850-pupd"
+ - reg: Base address and length of the memory resource used by the pullup/down
+ controller hardware module.
+
+The controller node also acts as a container for pin group configuration nodes.
+The names of these groups are ignored.
+
+Pin Group Node Properties:
+
+- groups: An array of strings, each string containing the name of a pin group.
+ Valid names are "cp0".."cp31".
+
+The pin configuration parameters use the generic pinconf bindings defined in
+pinctrl-bindings.txt in this directory. The supported parameters are
+bias-disable, bias-pull-up, bias-pull-down.

+* Pin configuration for TI IODELAY controller
+
+TI dra7 based SoCs such as am57xx have a controller for setting the IO delay

+ Binding for Xilinx Zynq Pinctrl
+
+Required properties:
+- compatible: "xlnx,zynq-pinctrl"
+- syscon: phandle to SLCR
+- reg: Offset and length of pinctrl space in SLCR
+
+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".
+
+Zynq's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, slew rate, etc.
+
+Each configuration node can consist of multiple nodes describing the pinmux and
+pinconf options. Those nodes can be pinmux nodes or pinconf nodes.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Required properties for pinmux nodes are:
+ - groups: A list of pinmux groups.
+ - function: The name of a pinmux function to activate for the specified set
+ of groups.
+
+Required properties for configuration nodes:
+One of:
+ - pins: a list of pin names
+ - groups: A list of pinmux groups.
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pinmux subnode:
+ groups, function
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pinconf subnode:
+ groups, pins, bias-disable, bias-high-impedance, bias-pull-up, slew-rate,
+ low-power-disable, low-power-enable
+
+ Valid arguments for 'slew-rate' are '0' and '1' to select between slow and fast
+ respectively.
