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>; + };
