Merge tag 'pwm/for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "This series contains a number of improvements to existing drivers,
  such as LPSS. Some drivers, such as renesas-tpu and rcar get support
  for more SoC generations. To round things off this fixes an issue with
  the sysfs interface"

* tag 'pwm/for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm:
  pwm: lpss: Only set update bit if we are actually changing the settings
