Merge tag 'pwm/for-5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "The changes for this cycle are across the board.

  The bulk of it is cleanups, but there's also new device support in
  some drivers as well as more conversions to the atomic API"
