+* TI Common Platform Interrupt Controller
+
+Common Platform Interrupt Controller (cp_intc) is used on
+OMAP-L1x SoCs and can support several configurable number
+of interrupts.
+
+Main node required properties:
+
+- compatible : should be:
+       "ti,cp-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,cp-intc";
+               interrupt-controller;
+               #interrupt-cells = <1>;
+               ti,intc-size = <101>;
+               reg = <0xfffee000 0x2000>;
+       };
