Merge tag 'pwm/for-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "After v5.19 had all drivers converted to the new atomic API and nobody
  has reported any breakage, this set of changes starts by dropping the
  legacy support.

  Some existing drivers get improvements and broader chip support and a
  new driver is added that emulates a PWM controller using a clock
  output.

  Other than that there's the usual bits of cleanups and minor fixes"
