   1 Device tree bindings for IR LED connected through SPI bus which is used as
   2 remote controller.
   3
   4 The IR LED switch is connected to the MOSI line of the SPI device and the data
   5 are delivered thourgh that.
   6
   7 Required properties:
   8         - compatible: should be "ir-spi-led".
   9
  10 Optional properties:
  11         - duty-cycle: 8 bit balue that represents the percentage of one period
  12           in which the signal is active.  It can be 50, 60, 70, 75, 80 or 90.
  13         - led-active-low: boolean value that specifies whether the output is
  14           negated with a NOT gate.
  15         - power-supply: specifies the power source. It can either be a regulator
  16           or a gpio which enables a regulator, i.e. a regulator-fixed as
  17           described in
  18           Documentation/devicetree/bindings/regulator/fixed-regulator.txt

  20 Example:
  21
  22         irled@0 {
  23                 compatible = "ir-spi-led";
  24                 reg = <0x0>;
  25                 spi-max-frequency = <5000000>;
  26                 power-supply = <&vdd_led>;
  27                 led-active-low;
  28                 duty-cycle = /bits/ 8 <60>;
  29         };
