Merge tag 'pwm/for-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "The Meson PWM controller driver gains support for the AXG series and a
  minor bug is fixed for the STMPE driver.

  To round things off, the class is now set for PWM channels exported
  via sysfs which allows non-root access, provided that the system has
  been configured accordingly"

* tag 'pwm/for-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm:
  pwm: meson: Add clock source configuration for Meson-AXG
  dt-bindings: pwm: Update bindings for the Meson-AXG
  pwm: stmpe: Fix wrong register offset for hwpwm=2 case
  pwm: Set class for exported channels in sysfs
