I tried to apply the series for a test, with the intent to queue this for
v6.7, but there are conflicts toward both v6.6-rc1 and my pin control
devel branch, so I can't.

Since we are at -rc5 and the kernel looks better after the patches
than before I think they should just be applied and not held back
by minor review nits or process. But i couldn't.

I'm fine with the series as they are, but it looks like we need to queue
it at v6.7-rc1 for v6.8 or you need to send it to Torvalds after he
merged GPIO and pin control for v6.7, either works for me!
