+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>;
+       };
