   1* OMAP Interrupt Controller
   2
   3OMAP2/3 are using a TI interrupt controller that can support several
   4configurable number of interrupts.
   5
   6Main node required properties:
   7
   8- compatible : should be:
   9        "ti,omap2-intc"
  10- interrupt-controller : Identifies the node as an interrupt controller
  11- #interrupt-cells : Specifies the number of cells needed to encode an
  12  interrupt source. The type shall be a <u32> and the value shall be 1.
  13
  14  The cell contains the interrupt number in the range [0-128].
  15- ti,intc-size: Number of interrupts handled by the interrupt controller.
  16- reg: physical base address and size of the intc registers map.
  17
  18Example:
  19
  20        intc: interrupt-controller@1 {
  21                compatible = "ti,omap2-intc";
  22                interrupt-controller;
  23                #interrupt-cells = <1>;
  24                ti,intc-size = <96>;
  25                reg = <0x48200000 0x1000>;
  26        };
