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>;
|
|
};
