Nintendo Wii (Hollywood) GPIO controller
Required properties:
- compatible: "nintendo,hollywood-gpio"
- reg: Physical base address and length of the controller's registers.
- gpio-controller: Marks the device node as a GPIO controller.
- #gpio-cells: Should be <2>. The first cell is the pin number and the
second cell is used to specify optional parameters:
- bit 0 specifies polarity (0 for normal, 1 for inverted).
Optional properties:
- ngpios: see Documentation/devicetree/bindings/gpio/gpio.txt
- interrupt-controller: Marks the device node as an interrupt controller.
- #interrupt-cells: Should be two.
- interrupts: Interrupt specifier for the controller's Broadway (PowerPC)
interrupt.
Example:
GPIO: gpio@d8000c0 {
#gpio-cells = <2>;
compatible = "nintendo,hollywood-gpio";
reg = <0x0d8000c0 0x40>;
gpio-controller;
ngpios = <24>;
