Allwinner Sunxi Interrupt Controller

Required properties:

- compatible : should be one of the following:

              "allwinner,sun4i-a10-ic"

              "allwinner,suniv-f1c100s-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.

Example:

intc: interrupt-controller {

	compatible = "allwinner,sun4i-a10-ic";

	reg = <0x01c20400 0x400>;

	interrupt-controller;

	#interrupt-cells = <1>;

};
