+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.

+ description:
+ The number of cells to define the interrupts. It must be 1 as the

+ 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.

+ 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.
