+* 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-parent: Empty for the interrupt controller itself
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells: The number of cells to define the interrupts. Should be 2.
+	The first cell is the IRQ number
+	The second cell is used to specify mode:
+		1 = low-to-high edge triggered
+		2 = high-to-low edge triggered
+		4 = active high level-sensitive
+		8 = active low level-sensitive
+		Default for internal sources should be set to 4 (active high).
+
+Examples:
+	intc: interrupt-controller {
+		compatible = "andestech,ativic32";
+		#interrupt-cells = <2>;
+		interrupt-controller;
+	};
