+Axis CRISv32 interrupt controller
+
+Required properties:
+- compatible: Compatible property value should be "axis,cris32-intc"
+
+- reg: Physical base address of the controller and length of memory mapped
+       region.
+
+- interrupt-controller : Identifies the node as an interrupt controller
+
+Example:
+
+interrupt-controller {
+	compatible = "axis,crisv32-intc";
+	interrupt-controller;
+	reg = <0xb001c000 0x1000>;
+	#interrupt-cells = <1>;
+};
