Merge tag 'pwm/for-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "This is a fairly big release cycle from the PWM framework's point of
  view.

  There's a large patcheset here which converts drivers to use the new
  devm_platform_ioremap_resource() helper and a bunch of minor fixes to
  existing drivers. Some of the existing drivers also add support for
  more hardware, such as Atmel SAMA 5D2 and Mediatek MT8183.

  Finally there's a couple of new drivers for Intel Keem Bay and LGM
  SoCs as well as the DesignWare PWM controller"
