- - 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,rcar-gpio.yaml
-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>;
- };

-Renesas RZ/N1 SoC Pinctrl node description.
-
-Pin controller node
--------------------
-Required properties:
-- compatible: SoC-specific compatible string "renesas,<soc-specific>-pinctrl"
- followed by "renesas,rzn1-pinctrl" as fallback. The SoC-specific compatible
- strings must be one of:
- "renesas,r9a06g032-pinctrl" for RZ/N1D
- "renesas,r9a06g033-pinctrl" for RZ/N1S
-- reg: Address base and length of the memory area where the pin controller
- hardware is mapped to.
-- clocks: phandle for the clock, see the description of clock-names below.
-- clock-names: Contains the name of the clock:
- "bus", the bus clock, sometimes described as pclk, for register accesses.
-
-Example:
- pinctrl: pin-controller@40067000 {
- compatible = "renesas,r9a06g032-pinctrl", "renesas,rzn1-pinctrl";
- reg = <0x40067000 0x1000>, <0x51000000 0x480>;
- clocks = <&sysctrl R9A06G032_HCLK_PINCONFIG>;
- clock-names = "bus";
- };
-
-Sub-nodes
----------
-
-The child nodes of the pin controller node describe a pin multiplexing
-function.
-
-- 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.
- 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;
- };
- };
-
- node-3 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
-
- sub-node-1 {
- 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 latter two formats when pins part of the same logical group need to
- have different generic pin configuration flags applied. Note that the generic
- pinconfig in node-3 does not apply to the sub-nodes.
-
- 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.
- Integers values in the "pinmux" argument list are assembled as:
- (PIN | MUX_FUNC << 8)
- where PIN directly corresponds to the pl_gpio pin number and MUX_FUNC is
- one of the alternate function identifiers defined in:
- <include/dt-bindings/pinctrl/rzn1-pinctrl.h>
- These identifiers collapse the IO Multiplex Configuration Level 1 and
- Level 2 numbers that are detailed in the hardware reference manual into a
- single number. The identifiers for Level 2 are simply offset by 10.
- Additional identifiers are provided to specify the MDIO source peripheral.
-
- Optional generic pinconf properties:
- - bias-disable - disable any pin bias
- - bias-pull-up - pull up the pin with 50 KOhm
- - bias-pull-down - pull down the pin with 50 KOhm
- - bias-high-impedance - high impedance mode
- - drive-strength - sink or source at most 4, 6, 8 or 12 mA
-
- Example:
- A serial communication interface with a TX output pin and an RX input pin.
-
- &pinctrl {
- pins_uart0: pins_uart0 {
- pinmux = <
- RZN1_PINMUX(103, RZN1_FUNC_UART0_I) /* UART0_TXD */
- RZN1_PINMUX(104, RZN1_FUNC_UART0_I) /* UART0_RXD */
- >;
- };
- };
-
- Example 2:
- Here we set the pull up on the RXD pin of the UART.
-
- &pinctrl {
- pins_uart0: pins_uart0 {
- pinmux = <RZN1_PINMUX(103, RZN1_FUNC_UART0_I)>; /* TXD */
-
- pins_uart6_rx {
- pinmux = <RZN1_PINMUX(104, RZN1_FUNC_UART0_I)>; /* RXD */
- bias-pull-up;
- };
- };
- };

+ description: |
+ 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.
+ Integers values in the "pinmux" argument list are assembled as:
+ (PIN | MUX_FUNC << 8)
+ where PIN directly corresponds to the pl_gpio pin number and
+ MUX_FUNC is one of the alternate function identifiers defined in:
+ <include/dt-bindings/pinctrl/rzn1-pinctrl.h>
+ These identifiers collapse the IO Multiplex Configuration Level 1
+ and Level 2 numbers that are detailed in the hardware reference
+ manual into a single number. The identifiers for Level 2 are simply
+ offset by 10. Additional identifiers are provided to specify the
+ MDIO source peripheral.
