+* Marvell Orion GPIO Controller
+
+Required properties:
+- compatible         : Should be "marvell,orion-gpio"
+- reg                : Address and length of the register set for controller.
+- gpio-controller    : So we know this is a gpio controller.
+- ngpio              : How many gpios this controller has.
+- interrupts	     : Up to 4 Interrupts for the controller.
+
+Optional properties:
+- mask-offset        : For SMP Orions, offset for Nth CPU
+
+Example:
+
+		gpio0: gpio@10100 {
+			compatible = "marvell,orion-gpio";
+			#gpio-cells = <2>;
+			gpio-controller;
+			reg = <0x10100 0x40>;
+			ngpio = <32>;
+			interrupts = <35>, <36>, <37>, <38>;
