1Device tree bindings for IR LED connected through SPI bus which is used as 2remote controller. 3 4The IR LED switch is connected to the MOSI line of the SPI device and the data 5are delivered thourgh that. 6 7Required properties: 8 - compatible: should be "ir-spi-led". 9 10Optional properties: 11 - duty-cycle: 8 bit value that represents the percentage of one period 12 in which the signal is active. It can be 50, 60, 70, 75, 80 or 90. 13 - led-active-low: boolean value that specifies whether the output is 14 negated with a NOT gate. 15 - power-supply: specifies the power source. It can either be a regulator 16 or a gpio which enables a regulator, i.e. a regulator-fixed as 17 described in 18 Documentation/devicetree/bindings/regulator/fixed-regulator.yaml 19 20Example: 21 22 irled@0 { 23 compatible = "ir-spi-led"; 24 reg = <0x0>; 25 spi-max-frequency = <5000000>; 26 power-supply = <&vdd_led>; 27 led-active-low; 28 duty-cycle = /bits/ 8 <60>; 29 }; 30
