Merge tag 'pwm/for-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Browse Source 
Pull pwm updates from Thierry Reding:
 "The majority of this batch is conversion of the PWM period and duty
  cycle to 64-bit unsigned integers, which is required so that some
  types of hardware can generate the full range of signals that they're
  capable of.

  The remainder is mostly minor fixes and cleanups"
