This patch series adds support for PWM "atomic" API and improve
the clock calculation.

Changes from v2 [1]:
 - Add Acked-by of Uwe in patch [234]/4.
 - Modify a condition to support normal polarity only.
 - Fix possible to output wrong a duty cycle when disabling in patch 1/4.
 - Fix overflow value on 32-bit arch in patch 4/4.

Changes from v1 [2]:
 - Remove workaround code of output pseudo low level for now because it is
   rejected on the ML.
 - Add a condition for polarity because the HW doesn't support polarity change
   in patch 1/4.
 - Improve the clock calculation in patch 4/4.

Remarks:
On the email thread of patch 2/4, we discuss about suspend/resume
handling and I suposed to improve it. However, I need more time
how to improve it. So, for now, I don't improve it on this patch series.
