+Conexant Digicolor Interrupt Controller
+
+Required properties:
+
+- compatible : should be "cnxt,cx92755-ic"
+- reg : Specifies base physical address and size of the MISC area, that is
+  where the interrupt controller registers are located
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+  interrupt source. The value shall be 1.
+
+Example:
+
+	intc: intc at f0000000 {
+		compatible = "cnxt,cx92755-ic";
+		interrupt-controller;
+		#interrupt-cells = <1>;
+		reg = <0xf0000000 0x1000>;
+	};
