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.
