29 maxim,fan-microvolt:
31 The supply voltage of the fan, either 5000000 uV or
35 maxim,fan-prescale:
37 Pre-scaling value, as per datasheet. Lower values
38 allow more fine-grained control of slower fans.
42 maxim,fan-target-rpm:
44 Initial requested fan rotation speed. If specified, the
45 driver selects closed-loop mode and the requested speed.
46 This ensures the fan is already running before userspace
