Merge tag 'pwm/for-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux

Pull pwm updates from Uwe Kleine-König:
 "This contains the usual mix of fixes, cleanups, two new drivers and
  several dt binding updates. The fixes are for minor issues that are
  already old (4.11-rc1 and 3.9-rc1) and were found by code review and
  not during usage, so I didn't sent them for earlier inclusion.

  The changes to include/linux/mfd/stm32-timers.h and
  drivers/counter/stm32-timer-cnt.c are part of an immutable branch that
  will also be included in the mfd and counter pulls. It changes some
  register definitions and affects the pwm-stm32 driver.

  Thanks go to Andy Shevchenko, AngeloGioacchino Del Regno, Conor
  Dooley, David Lechner, Dhruva Gole, Drew Fustini, Frank Li, Jeff
  Johnson, Junyi Zhao, Kelvin Zhang, Krzysztof Kozlowski, Lee Jones,
  Linus Walleij, Linus Walleij, Michael Hennerich, Nicola Di Lieto,
  Nicolas Ferre, Nuno Sa, Paul Cercueil, Raag Jadav, Rob Herring, Sean
  Anderson, Sean Young, Shenwei Wang, Stefan Wahren, Trevor Gamblin,
  Tzung-Bi Shih, Vincent Whitchurch and William Breathitt Gray for their
  contributions to this pull request; they authored changes, spend time
  reviewing changes and coordinated the above mentioned immutable
  branch"
