+* ARM Vectored Interrupt Controller
+
+One or more Vectored Interrupt Controllers (VIC's) can be connected in an ARM
+system for interrupt routing. For multiple controllers they can either be
+nested or have the outputs wire-OR'd together.
+
+Required properties:
+
+- compatible : should be one of
+ "arm,pl190-vic"
+ "arm,pl192-vic"
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : The number of cells to define the interrupts. Must be 1 as
+ the VIC has no configuration options for interrupt sources. The cell is a u32
+ and defines the interrupt number.
+- reg : The register bank for the VIC.
+
+Optional properties:
+
+- interrupts : Interrupt source for parent controllers if the VIC is nested.
+
+Example:
+
+ vic0: interrupt-controller@60000 {
+ compatible = "arm,pl192-vic";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ reg = <0x60000 0x1000>;
+ };
