+* Andestech Internal Vector Interrupt Controller
+
+The Internal Vector Interrupt Controller (IVIC) is a basic interrupt controller
+suitable for a simpler SoC platform not requiring a more sophisticated and
+bigger External Vector Interrupt Controller.
+
+
+Main node required properties:
+
+- compatible : should at least contain "andestech,ativic32".
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells: 1 cells and refer to interrupt-controller/interrupts
+
+Examples:
+ intc: interrupt-controller {
+ compatible = "andestech,ativic32";
+ #interrupt-cells = <1>;
+ interrupt-controller;
+ };
