Device tree bindings for IR LED connected through SPI bus which is used as remote controller. The IR LED switch is connected to the MOSI line of the SPI device and the data are delivered thourgh that. Required properties: - compatible: should be "ir-spi-led". Optional properties: - duty-cycle: 8 bit balue that represents the percentage of one period in which the signal is active. It can be 50, 60, 70, 75, 80 or 90. - led-active-low: boolean value that specifies whether the output is negated with a NOT gate. - power-supply: specifies the power source. It can either be a regulator or a gpio which enables a regulator, i.e. a regulator-fixed as described in Documentation/devicetree/bindings/regulator/fixed-regulator.txt Example: irled@0 { compatible = "ir-spi-led"; reg = <0x0>; spi-max-frequency = <5000000>; power-supply = <&vdd_led>; led-active-low; duty-cycle = /bits/ 8 <60>; };
