+Allwinner Sunxi Interrupt Controller
+
+Required properties:
+
+- compatible : should be "allwinner,sunxi-ic"
+- reg : Specifies base physical address and size of the registers.
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The value shall be 1.
+
+The interrupt sources are as follows:
