This series fixes minor issues in config callback and allows for on the
fly updates for pwm period and duty cycle. This is mainly intended to
allow pwm omap dmtimer to be used to generate a 1PPS signal that can be
syncronized to PTP clock in CPTS module in AM335x and AM57xx SoCs.

Series tested after applying the following series:
- https://patchwork.kernel.org/patch/11379875/
- https://patchwork.kernel.org/project/linux-omap/list/?series=246183

  pwm: omap-dmtimer: Fix pwm enabling sequence
  pwm: omap-dmtimer: Do not disable pwm before changing
    period/duty_cycle
  pwm: omap-dmtimer: Implement .apply callback
