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.

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.

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.

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.
