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>; |
|
};
