1* ARM Vectored Interrupt Controller
2
3One or more Vectored Interrupt Controllers (VIC's) can be connected in an ARM
4system for interrupt routing. For multiple controllers they can either be
5nested or have the outputs wire-OR'd together.
6
7Required properties:
8
9- compatible : should be one of
10 "arm,pl190-vic"
11 "arm,pl192-vic"
12- interrupt-controller : Identifies the node as an interrupt controller
13- #interrupt-cells : The number of cells to define the interrupts. Must be 1 as
14 the VIC has no configuration options for interrupt sources. The cell is a u32
15 and defines the interrupt number.
16- reg : The register bank for the VIC.
17
18Optional properties:
19
20- interrupts : Interrupt source for parent controllers if the VIC is nested.
21
22Example:
23
24 vic0: interrupt-controller@60000 {
25 compatible = "arm,pl192-vic";
26 interrupt-controller;
27 #interrupt-cells = <1>;
28 reg = <0x60000 0x1000>;
29 };
