+Mediatek MT65xx/MT67xx/MT81xx sysirq
|
|
|
|
Mediatek SOCs sysirq support controllable irq inverter for each GIC SPI
|
|
interrupt.
|
|
|
|
Required properties:
|
|
- compatible: should be
|

|
|
"mediatek,mt8135-sysirq", "mediatek,mt6577-sysirq": for MT8135
|
|

|
- interrupt-controller : Identifies the node as an interrupt controller
|
|
- #interrupt-cells : Use the same format as specified by GIC in 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. Could be multiple bases here. Ex: mt6797 needs 2 reg, others
|
|
need 1.
|
|
|
|
Example:
|
|
sysirq: intpol-controller@10200620 {
|
|
compatible = "mediatek,mt6797-sysirq",
|
|
"mediatek,mt6577-sysirq";
|
|
interrupt-controller;
|
|
#interrupt-cells = <3>;
|
|
interrupt-parent = <&gic>;
|
|
reg = <0 0x10220620 0 0x20>,
|
|
<0 0x10220690 0 0x10>;
|
|
};
