+* Central Interrupt Unit v3
+
+Properties:
+- compatible: "cavium,octeon-7890-ciu3"
+
+  Compatibility with 78XX and 73XX SOCs.
+
+- interrupt-controller:  This is an interrupt controller.
+
+- reg: The base address of the CIU's register bank.
+
+- #interrupt-cells: Must be <2>.  The first cell is source number.
+  The second cell indicates the triggering semantics, and may have a
+  value of either 4 for level semantics, or 1 for edge semantics.
+
+Example:
+	interrupt-controller@1010000000000 {
+		compatible = "cavium,octeon-7890-ciu3";
+		interrupt-controller;
+		/* Interrupts are specified by two parts:
+		 * 1) Source number (20 significant bits)
+		 * 2) Trigger type: (4 == level, 1 == edge)
+		 */
+		#address-cells = <0>;
+		#interrupt-cells = <2>;
+		reg = <0x10100 0x00000000 0x0 0xb0000000>;
+	};
