  13   One or more Vectored Interrupt Controllers (VIC's) can be connected in an
  14   ARM system for interrupt routing.  For multiple controllers they can either
  15   be nested or have the outputs wire-OR'd together.

  32       The number of cells to define the interrupts.  It must be 1 as the
  33       VIC has no configuration options for interrupt sources. The single
  34       cell defines the interrupt number.

  43     description:
  44       A one cell big bit mask of valid interrupt sources. Each bit
  45       represents single interrupt source, starting from source 0 at
  46       LSb and ending at source 31 at MSb. A bit that is set means
  47       that the source is wired and clear means otherwise. If unspecified,
  48       defaults to all valid.

  52     description:
  53       A one cell big bit mask of interrupt sources that can be configured
  54       as wake up source for the system. Order of bits is the same as for
  55       valid-mask property. A set bit means that this interrupt source
  56       can be configured as a wake up source for the system. If unspecied,
  57       defaults to all interrupt sources configurable as wake up sources.
