Merge tag 'pwm/for-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "This set of changes contains support for PWM signal capture in the STi
  driver as well as support for the PWM controller found on Meson SoCs.
  There's also support added for the MediaTek MT2701 and SunXi H3 to the
  existing drivers.

  Other than that there's a fair set of miscellaneous cleanups and fixes
  across the board"
