+* Central Interrupt Unit
+
+Properties:
+- compatible: "cavium,octeon-3860-ciu"
+
+  Compatibility with all cn3XXX, cn5XXX and cn63XX 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 the bank within
+   the CIU and may have a value of 0 or 1.  The second cell is the bit
+   within the bank and may have a value between 0 and 63.
+
+Example:
+       interrupt-controller@1070000000000 {
+               compatible = "cavium,octeon-3860-ciu";
+               interrupt-controller;
+               /* Interrupts are specified by two parts:
+                * 1) Controller register (0 or 1)
+                * 2) Bit within the register (0..63)
+                */
+               #interrupt-cells = <2>;
+               reg = <0x10700 0x00000000 0x0 0x7000>;
