| - 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. |
| - interrupt-parent: phandle of the parent interrupt controller. |

| Example: |
| |
| GPIO: gpio@d8000c0 { |
| #gpio-cells = <2>; |
| compatible = "nintendo,hollywood-gpio"; |
| reg = <0x0d8000c0 0x40>; |
| gpio-controller; |
| ngpios = <24>; |
