+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>;
+ };
