+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 at 10200100 {
+ compatible = "mediatek,mt6589-sysirq", "mediatek,mt6577-sysirq";
+ interrupt-controller;
+ #interrupt-cells = <3>;
+ interrupt-parent = <&gic>;
+ reg = <0 0x10200100 0 0x1c>;
+ };
