-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>;
- };
-};
- compatible: One of:
- "ingenic,jz4740-pinctrl"
+ - "ingenic,jz4725b-pinctrl"
- "ingenic,jz4770-pinctrl"
- "ingenic,jz4780-pinctrl"
- reg: Address range of the pinctrl registers.
-GPIO sub-nodes
---------------
+Required properties for sub-nodes (GPIO chips):
+-----------------------------------------------
-The pinctrl node can have optional sub-nodes for the Ingenic GPIO driver;
-please refer to ../gpio/ingenic,gpio.txt.
+ - 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/gpio.txt for more details.
Example:
pinctrl: pin-controller@10010000 {
compatible = "ingenic,jz4740-pinctrl";
reg = <0x10010000 0x400>;
+ #address-cells = <1>;

+
+ gpa: gpio@0 {
