1 | * ARM Vectored Interrupt Controller | ||
2 | |||
3 | One or more Vectored Interrupt Controllers (VIC's) can be connected in an ARM | ||
4 | system for interrupt routing. For multiple controllers they can either be | ||
5 | nested or have the outputs wire-OR'd together. | ||
6 | |||
7 | Required 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 | |||
18 | Optional properties: | ||
19 | |||
20 | - interrupts : Interrupt source for parent controllers if the VIC is nested. | ||
21 | |||
22 | Example: | ||
23 | |||
24 | vic0: interrupt-controller@60000 { | ||
25 | compatible = "arm,pl192-vic"; | ||
26 | interrupt-controller; | ||
27 | #interrupt-cells = <1>; | ||
28 | reg = <0x60000 0x1000>; | ||
