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>;
|
|
};
|
|
};
