+  - 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.
