    1 * TI Common Platform Interrupt Controller
    2 
    3 Common Platform Interrupt Controller (cp_intc) is used on
    4 OMAP-L1x SoCs and can support several configurable number
    5 of interrupts.
    6 
    7 Main node required properties:
    8 
    9 - compatible : should be:
   10         "ti,cp-intc"
   11 - interrupt-controller : Identifies the node as an interrupt controller
   12 - #interrupt-cells : Specifies the number of cells needed to encode an
   13   interrupt source. The type shall be a <u32> and the value shall be 1.
   14 
   15   The cell contains the interrupt number in the range [0-128].
   16 - ti,intc-size: Number of interrupts handled by the interrupt controller.
   17 - reg: physical base address and size of the intc registers map.
   18 
   19 Example:
   20 
   21         intc: interrupt-controller@1 {
   22                 compatible = "ti,cp-intc";
   23                 interrupt-controller;
   24                 #interrupt-cells = <1>;
   25                 ti,intc-size = <101>;
   26                 reg = <0xfffee000 0x2000>;
   27         };
