   1 Mediatek 65xx/81xx sysirq
   2
   3 Mediatek SOCs sysirq support controllable irq inverter for each GIC SPI
   4 interrupt.
   5
   6 Required properties:
   7 - compatible: should be one of:
   8         "mediatek,mt8173-sysirq"
   9         "mediatek,mt8135-sysirq"
  10         "mediatek,mt8127-sysirq"
  11         "mediatek,mt6589-sysirq"
  12         "mediatek,mt6582-sysirq"
  13         "mediatek,mt6577-sysirq"
  14 - interrupt-controller : Identifies the node as an interrupt controller
  15 - #interrupt-cells : Use the same format as specified by GIC in
  16   Documentation/devicetree/bindings/arm/gic.txt
  17 - interrupt-parent: phandle of irq parent for sysirq. The parent must
  18   use the same interrupt-cells format as GIC.
  19 - reg: Physical base address of the intpol registers and length of memory
  20   mapped region.

  23         sysirq: interrupt-controller@10200100 {
  24                 compatible = "mediatek,mt6589-sysirq", "mediatek,mt6577-sysirq";
  25                 interrupt-controller;
  26                 #interrupt-cells = <3>;
  27                 interrupt-parent = <&gic>;
  28                 reg = <0 0x10200100 0 0x1c>;
