Merge tag 'pwm/for-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "This contains mostly various fixes, cleanups and some conversions to
  the atomic API. One noteworthy change is that PWM consumers can now
  pass a hint to the PWM core about the PWM usage, enabling PWM
  providers to implement various optimizations.

  There's also a fair bit of simplification here with the addition of
  some device-managed helpers as well as unification between the DT and
  ACPI firmware interfaces"
