Kernel-4.18.0-80.el8_gpio-ir-tx

Device tree bindings for IR LED connected through gpio pin which is used as
remote controller transmitter.

Required properties:
- compatible: should be “gpio-ir-tx”.
- gpios : Should specify the IR LED GPIO, see “gpios property” in
Documentation/devicetree/bindings/gpio/gpio.txt. Active low LEDs
should be indicated using flags in the GPIO specifier.

Example:
irled@0 {
compatible = “gpio-ir-tx”;
gpios = <&gpio1 2 GPIO_ACTIVE_HIGH>;
};
