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 value 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.yaml
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>;
};
