Ingenic jz47xx GPIO controller
That the Ingenic GPIO driver node must be a sub-node of the Ingenic pinctrl
driver node.
Required properties:
--------------------
- compatible: Must contain one of:
- "ingenic,jz4740-gpio"
- "ingenic,jz4770-gpio"
- "ingenic,jz4780-gpio"
- reg: The GPIO bank number.
- interrupt-controller: Marks the device node as an interrupt controller.
- interrupts: Interrupt specifier for the controllers interrupt.
- #interrupt-cells: Should be 2. Refer to
../interrupt-controller/interrupts.txt for more details.
- 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.
- gpio-ranges: Range of pins managed by the GPIO controller. Refer to
'gpio.txt' in this directory for more details.
Example:
--------
&pinctrl {
#address-cells = <1>;
#size-cells = <0>;
gpa: gpio@0 {
compatible = "ingenic,jz4740-gpio";
reg = <0>;
gpio-controller;
gpio-ranges = <&pinctrl 0 0 32>;
#gpio-cells = <2>;
interrupt-controller;
#interrupt-cells = <2>;
interrupt-parent = <&intc>;
interrupts = <28>;
};
};

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>;
};
