* 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>;
};
