    1 * OMAP Interrupt Controller
    2 
    3 OMAP2/3 are using a TI interrupt controller that can support several
    4 configurable number of interrupts.
    5 
    6 Main 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 
   18 Example:
   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         };
