Merge tag 'pwm/for-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "This contains a bunch of cleanups and simplifications across the
  board, as well as a number of small fixes.

  Perhaps the most notable change here is the addition of an API that
  allows PWMs to be used in atomic contexts, which is useful when time-
  critical operations are involved, such as using a PWM to generate IR
  signals.

  Finally, I have decided to step down as PWM subsystem maintainer. Due
  to other responsibilities I have lately not been able to find the time
  that the subsystem deserves and Uwe, who has been helping out a lot
  for the past few years and has many things planned for the future, has
  kindly volunteered to take over. I have no doubt that he will be a
  suitable replacement"
