What does the '4' represent, an internal channel number? It should
probably be omitted if the PM8350 only has a single output PWM
port.


pm8350c has four PWMs, but I think we can drop the '4' here.

I don't think it should be enabled by default, there may be boards with
the PM8350C that don't use the PWM.

Okay.
