title: ARM Vectored Interrupt Controller
maintainers:
- Rob Herring <robh@kernel.org>
description: |+
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.
allOf:

properties:
compatible:
enum:
- arm,pl190-vic
- arm,pl192-vic
- arm,versatile-vic
interrupt-controller: true
"#interrupt-cells":
const: 1
description:
The number of cells to define the interrupts. It must be 1 as the
VIC has no configuration options for interrupt sources. The single
cell defines the interrupt number.
reg:
maxItems: 1
interrupts:
maxItems: 1
valid-mask:
description:
A one cell big bit mask of valid interrupt sources. Each bit
represents single interrupt source, starting from source 0 at
LSb and ending at source 31 at MSb. A bit that is set means
that the source is wired and clear means otherwise. If unspecified,
defaults to all valid.
$ref: /schemas/types.yaml#/definitions/uint32
valid-wakeup-mask:
description:
A one cell big bit mask of interrupt sources that can be configured
as wake up source for the system. Order of bits is the same as for
valid-mask property. A set bit means that this interrupt source
can be configured as a wake up source for the system. If unspecied,
defaults to all interrupt sources configurable as wake up sources.
