-features are provided, including PWM frequency control, temperature hysteresis,
-dual tachometer measurements, and fan health monitoring.

Not sure if that is a good idea. It would make more sense to standardize the
properties needed by the driver/chip instead (see existing dts files in the kernel).

Do we have a general guideline on how to handle such trivial bindings ?
I normally leave it up to the driver author to decide one way or another.

This device is certainly not trivial, the binding is just incomplete.
Device specific fan controller bindings are something I'm just going
to reject until someone comes up with something common.

Not really. I debate (with myself) just getting rid of it as I suspect
lots of bindings are just incomplete. Like should supplies be
required? But it's convenient to have and not duplicate a bunch of
boilerplate.

Me too.
This one looks simple enough to be in trivial-devices, so I'll take
having a schema over not.

Applied, thanks!
