      1Bindings for fan connected to GPIO lines
      2
      3Required properties:
      4- compatible : "gpio-fan"
      5
      6Optional properties:
      7- gpios: Specifies the pins that map to bits in the control value,
      8  ordered MSB-->LSB.
      9- gpio-fan,speed-map: A mapping of possible fan RPM speeds and the
     10  control value that should be set to achieve them. This array
     11  must have the RPM values in ascending order.
     12- alarm-gpios: This pin going active indicates something is wrong with
     13  the fan, and a udev event will be fired.
     14- #cooling-cells: If used as a cooling device, must be <2>
     15  Also see:
     16  Documentation/devicetree/bindings/thermal/thermal-cooling-devices.yaml
     17  min and max states are derived from the speed-map of the fan.
     18
     19Note: At least one the "gpios" or "alarm-gpios" properties must be set.

     22
     23	gpio_fan {
     24		compatible = "gpio-fan";
     25		gpios = <&gpio1 14 1
     26			 &gpio1 13 1>;
     27		gpio-fan,speed-map = <0    0
     28				      3000 1
     29				      6000 2>;
     30		alarm-gpios = <&gpio1 15 1>;
     31	};
     32	gpio_fan_cool: gpio_fan {
     33		compatible = "gpio-fan";
     34		gpios = <&gpio2 14 1
     35			 &gpio2 13 1>;
     36		gpio-fan,speed-map =	<0    0>,
     37					<3000 1>,
     38					<6000 2>;
     39		alarm-gpios = <&gpio2 15 1>;
     40		#cooling-cells = <2>; /* min followed by max */
     41	};
