I didn't look in detail into the patch yet, but I think the review
feedback here is misleading. There is no promise about a hardware state
for a disabled channel. The only objective is to save power.
Having said that, it's *nice* to drive the inactive level, but if that
isn't easily possible (e.g. because the output goes to high-Z on
disable) the primary objective is to save power.
So I guess the feedback is OK, but not "High".

This is in the same category. It's a bit surprising, but well in the
limits of what a PWM consumer must expect.
Best regards
Uwe
