^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) Bindings for fan connected to GPIO lines
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) - compatible : "gpio-fan"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) Optional properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) - gpios: Specifies the pins that map to bits in the control value,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8)   ordered MSB-->LSB.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) - gpio-fan,speed-map: A mapping of possible fan RPM speeds and the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10)   control value that should be set to achieve them. This array
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)   must have the RPM values in ascending order.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) - alarm-gpios: This pin going active indicates something is wrong with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13)   the fan, and a udev event will be fired.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) - #cooling-cells: If used as a cooling device, must be <2>
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)   Also see:

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)   min and max states are derived from the speed-map of the fan.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Note: At least one the "gpios" or "alarm-gpios" properties must be set.
