+* 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>;
+        };
