My impression is that there are a lot of things that could easily be
done to improve the state of PWM drivers, but I don't care about the
order in which they are done. My main issue is the lack of a subsystem
core driver, which both you and Bill have patches for. It's clear that
other people have other issues and want to see their problems addressed
first.

I also think that the pwm code is simple enough that we don't have
to worry too much about the order that things are done in. Any patch
that is making the code better should just get in and not have to
wait for something else to be completed first.

What we do need now is a maintainer that can coordinate the patches
and merge the ones that have been agreed on. Or multiple maintainers.
