| 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>; |
| }; |
