    1 * ARM Vectored Interrupt Controller
    2 
    3 One or more Vectored Interrupt Controllers (VIC's) can be connected in an ARM
    4 system for interrupt routing.  For multiple controllers they can either be
    5 nested or have the outputs wire-OR'd together.
    6 
    7 Required properties:
    8 
    9 - compatible : should be one of
   10         "arm,pl190-vic"
   11         "arm,pl192-vic"
   12 - interrupt-controller : Identifies the node as an interrupt controller
   13 - #interrupt-cells : The number of cells to define the interrupts.  Must be 1 as
   14   the VIC has no configuration options for interrupt sources.  The cell is a u32
   15   and defines the interrupt number.
   16 - reg : The register bank for the VIC.
   17 
   18 Optional properties:
   19 
   20 - interrupts : Interrupt source for parent controllers if the VIC is nested.
   21 - valid-mask : A one cell big bit mask of valid interrupt sources. Each bit
   22   represents single interrupt source, starting from source 0 at LSb and ending
   23   at source 31 at MSb. A bit that is set means that the source is wired and
   24   clear means otherwise. If unspecified, defaults to all valid.
   25 - valid-wakeup-mask : A one cell big bit mask of interrupt sources that can be
   26   configured as wake up source for the system. Order of bits is the same as for
   27   valid-mask property. A set bit means that this interrupt source can be
   28   configured as a wake up source for the system. If unspecied, defaults to all
   29   interrupt sources configurable as wake up sources.
   30 
   31 Example:
   32 
   33         vic0: interrupt-controller@60000 {
   34                 compatible = "arm,pl192-vic";
   35                 interrupt-controller;
   36                 #interrupt-cells = <1>;
   37                 reg = <0x60000 0x1000>;
   38 
   39                 valid-mask = <0xffffff7f>;
   40                 valid-wakeup-mask = <0x0000ff7f>;
   41         };
