1 Device tree bindings for IR LED connected through pwm pin which is used as
2 remote controller transmitter.
5 - compatible: should be "pwm-ir-tx".
6 - pwms : PWM property to point to the PWM device (phandle)/port (id)
7 and to specify the period time to be used: <&phandle id period_ns>;
11 compatible = "pwm-ir-tx";
12 pwms = <&pwm0 0 10000000>;
