Specify #pwm-cells on pwm@11006000 to make it actually usable.

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?

Best regards

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

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

There's little point in setting this to 3 if the driver doesn't support
it. The core should catch misconfiguration, but that's more of a fail-
safe and if we can just avoid this from the start by not allowing anyone
to specify inversed polarity that seems like a good idea.
