     1 Socionext SynQuacer External Interrupt Unit (EXIU)
    2 
    3 The Socionext Synquacer SoC has an external interrupt unit (EXIU)
    4 that forwards a block of 32 configurable input lines to 32 adjacent
    5 level-high type GICv3 SPIs.
    6 
    7 Required properties:
    8 
    9 - compatible           : Should be "socionext,synquacer-exiu".
   10 - reg                  : Specifies base physical address and size of the
   11                          control registers.
   12 - interrupt-controller : Identifies the node as an interrupt controller.
   13 - #interrupt-cells     : Specifies the number of cells needed to encode an
   14                          interrupt source. The value must be 3.
   15 - socionext,spi-base   : The SPI number of the first SPI of the 32 adjacent
   16                          ones the EXIU forwards its interrups to.
   17 
   18 Notes:
   19 
   20 - Only SPIs can use the EXIU as an interrupt parent.
   21 
   22 Example:
   23 
   24         exiu: interrupt-controller@510c0000 {
   25                 compatible = "socionext,synquacer-exiu";
   26                 reg = <0x0 0x510c0000 0x0 0x20>;
   27                 interrupt-controller;
   28                 interrupt-parent = <&gic>;
   29                 #interrupt-cells = <3>;
   30                 socionext,spi-base = <112>;
   31         };
