- 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>;
};

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.
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 must be managed by the pin
controller driver internally, while software driven IO direction has to
be explicitly selected when multiple options are available.
properties:
pinmux:
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.
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>

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;
};
};
};
