* OMAP Interrupt Controller

OMAP2/3 are using a TI interrupt controller that can support several
configurable number of interrupts.

Main node required properties:

- compatible : should be:
	"ti,omap2-intc"
- interrupt-controller : Identifies the node as an interrupt controller
- #interrupt-cells : Specifies the number of cells needed to encode an
  interrupt source. The type shall be a <u32> and the value shall be 1.

  The cell contains the interrupt number in the range [0-128].
- ti,intc-size: Number of interrupts handled by the interrupt controller.
- reg: physical base address and size of the intc registers map.

Example:

	intc: interrupt-controller@1 {
		compatible = "ti,omap2-intc";
		interrupt-controller;
		#interrupt-cells = <1>;
		ti,intc-size = <96>;
		reg = <0x48200000 0x1000>;
	};
