Mediatek 65xx/81xx sysirq



Mediatek SOCs sysirq support controllable irq inverter for each GIC SPI

interrupt.



Required properties:

- compatible: should be one of:

	"mediatek,mt8135-sysirq"

	"mediatek,mt8127-sysirq"

	"mediatek,mt6589-sysirq"

	"mediatek,mt6582-sysirq"

	"mediatek,mt6577-sysirq"

- interrupt-controller : Identifies the node as an interrupt controller

- #interrupt-cells : Use the same format as specified by GIC in

  Documentation/devicetree/bindings/arm/gic.txt

- interrupt-parent: phandle of irq parent for sysirq. The parent must

  use the same interrupt-cells format as GIC.

- reg: Physical base address of the intpol registers and length of memory

  mapped region.



Example:

	sysirq: interrupt-controller@10200100 {

		compatible = "mediatek,mt6589-sysirq", "mediatek,mt6577-sysirq";

		interrupt-controller;

		#interrupt-cells = <3>;

		interrupt-parent = <&gic>;

		reg = <0 0x10200100 0 0x1c>;

	};
