Optional properties:
- interrupts : Interrupt source for parent controllers if the VIC is nested.
+- valid-mask : 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 : 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
