+Conexant Digicolor Interrupt Controller
+
+Required properties:
+
+- compatible : should be "cnxt,cx92755-ic"
+- reg : Specifies base physical address and size of the interrupt controller
+  registers (IC) area
+- 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.
+- syscon: A phandle to the syscon node describing UC registers
+
+Example:
+
+       intc: interrupt-controller@f0000040 {
+               compatible = "cnxt,cx92755-ic";
+               interrupt-controller;
+               #interrupt-cells = <1>;
+               reg = <0xf0000040 0x40>;
+               syscon = <&uc_regs>;
+       };
