+Realtek RTL8186 SoC interrupt controller
+
+Required properties:
+
+- compatible : should be "realtek,rtl8186-intc"
+- 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.
+- reg : Specifies base physical address and size of the registers.
+
+Example:
+
+intc: interrupt-controller@1d010000 {
+	compatible = "realtek,rtl8186-intc";
+	interrupt-controller;
+	#interrupt-cells = <1>;
+	reg = <0x1d010000 0x8>;
+};
