Subject: [PATCH 0/2] pwm: ab8500: Fix .apply() and implement .get_state()

Hello,

during review of my previous pwm-ab8500 patch I learned that there is a
(somewhat) publically available reference manual. Reading in it showed
that .apply() is still more broken that I assumed by just reading the
code.

This series first fixes .apply() to not be off by a factor of ~3000 and
then adds a .get_state() callback.

Note this is only compile tested as I don't have the hardware.
Also note this breaks all consumers that relied on the previously broken
behaviour.

  pwm: ab8500: Fix calculation of duty and period
  pwm: ab8500: Implement .get_state()
