Device-Tree bindings for GPIO IR receiver
Required properties:
- compatible: should be "gpio-ir-receiver".
- gpios: specifies GPIO used for IR signal reception.
Optional properties:
- min-delay: minimum delay(ms) to send IR event reset for raw IR decoding.
- linux,rc-map-name: Linux specific remote control map name.
- allowed-protos: 64 bit integer, platform specific allowed
IR protocols.
Example node:
ir: ir-receiver {
compatible = "gpio-ir-receiver";
gpios = <&gpio0 19 1>;
min-delay = <500>;
linux,rc-map-name = "rc-rc6-mce";
allowed-protos = <0x00000000 0x00000080>;
};
