Merge tag 'pwm/for-4.17-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 adds support for more generations of the RCar
  controller as well as runtime PM support. The JZ4740 driver gains
  support for device tree and can now be used on all Ingenic SoCs.

  Rounding things off is a random assortment of fixes and cleanups all
  across the board"
