Device-Tree bindings for Mediatek consumer IR controller
found in Mediatek SoC family
Required properties:
- compatible : "mediatek,mt7623-cir"
- clocks : list of clock specifiers, corresponding to
entries in clock-names property;
- clock-names : should contain "clk" entries;
- interrupts : should contain IR IRQ number;
- reg : should contain IO map address for IR.
Optional properties:
- linux,rc-map-name : see rc.txt file in the same directory.
Example:
cir: cir@10013000 {
compatible = "mediatek,mt7623-cir";
reg = <0 0x10013000 0 0x1000>;
interrupts = <GIC_SPI 87 IRQ_TYPE_LEVEL_LOW>;
clocks = <&infracfg CLK_INFRA_IRRX>;
clock-names = "clk";
linux,rc-map-name = "rc-rc6-mce";
};
