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>; }
