[PATCH v2 0/2] Add PWM fan support to Rock 5B board

[Cristian Ciocaltea]

This patch series enables support for the PWM controlled heat sink fan 
on the Rock 5B SBC and, additionally, converts the hwmon PWM fan bindings 
to DT schema format.

Changes in v2:
 - Updated PATCH 1/2 according to Rob's review
 - Added Reviewed-by from Christopher to PATCH 2/2
 - v1: https://lore.kernel.org/lkml/20230403105052.426135-1-cristian.ciocaltea@collabora.com/

I'm not so sure I'd allow for more than 1 if the example is the only 
case we can find. More than 1 implies you have multiple fans controlled 
by 1 PWM. What do you do with the tach data other than display it or 
detect a stuck fan. You can't really implement any control loop unless 
you average the rpm's? I suppose there could be h/w, so okay.

Not part of the original binding. It's not that useful in general if 
there's only 1 entry. It's completely useless if the name is not defined 
for the OS to use. So drop it.

Just duplicating the same text from thermal-cooling-devices.yaml is 
pointless.

As this is globally the only allowed value, you don't need to duplicate 
this either.

'"#cooling-cells": true"' is sufficient.

I will drop the 3rd example and use 'maxItems: 1' here. Same for
pulses-per-revolution below.

only the second one of course. According to earlier talks the dts patch
does already follow the text binding, so the yaml conversion is actually
not a requirement for it.

So I picked the dts patch let the binding sort itself when people have
time for it :-) .


Looking at the mail b4 created, I guessed this would also be visible
with the subject saying (subset) and the listed commits only showing

Kind of, sure, but I figured it doesn't hurt asking to avoid the situation
(again) where I apply a patch and then get a nice e-mail telling me that
some other branch also applied the same patch.

no worries and yes better save than sorry.
Though you had me worried for a bit that somehow the mail b4 generated
for me was faulty ;-)
