3 should be possible, too. The driver does only support one
polarity, so it's not really needed, but would be nice for consistency?

Thierry, what's your take here?

Other than that: Who would pick this up, I assume it to go via an ARM
tree together with the 2nd patch in this series?

The DT patch should go through my tree once all questions are answered and the dt-binding patch got accpeted by PWM maintainer.

Regards,
Matthias


The questions here are still open and both patches unapplied. :-\

Best regards
