+* Marvell Orion Interrupt controller
+
+Required properties
+- compatible :  Should be "marvell,orion-intc"
+- #interrupt-cells: Specifies the number of cells needed to encode an
+  interrupt source. Supported value is <1>
+- interrupt-controller : So that its clear its an interrupt controller.
+Optional properties
+- reg : Not used yet, but will contain the interrupt mask address
