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>;
|
|
}
