1+Mediatek 65xx/67xx/81xx sysirq
2
3Mediatek SOCs sysirq support controllable irq inverter for each GIC SPI
4interrupt.
5
6Required properties:
7- compatible: should be one of:
8 "mediatek,mt8173-sysirq"
9 "mediatek,mt8135-sysirq"
10 "mediatek,mt8127-sysirq"
11 "mediatek,mt6795-sysirq"
12 "mediatek,mt6755-sysirq"
13 "mediatek,mt6592-sysirq"
14 "mediatek,mt6589-sysirq"
15 "mediatek,mt6582-sysirq"
16 "mediatek,mt6580-sysirq"
17 "mediatek,mt6577-sysirq"
18 "mediatek,mt2701-sysirq"
19- interrupt-controller : Identifies the node as an interrupt controller
20- #interrupt-cells : Use the same format as specified by GIC in arm,gic.txt.
21- interrupt-parent: phandle of irq parent for sysirq. The parent must
22 use the same interrupt-cells format as GIC.
23- reg: Physical base address of the intpol registers and length of memory
24 mapped region.

26Example:
27 sysirq: interrupt-controller@10200100 {
28 compatible = "mediatek,mt6589-sysirq", "mediatek,mt6577-sysirq";
29 interrupt-controller;
30 #interrupt-cells = <3>;
31 interrupt-parent = <&gic>;
32 reg = <0 0x10200100 0 0x1c>;
33 };
