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