Merge tag 'pwm/for-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux
Pull pwm updates from Uwe Kleine-König:
"This contains the usual amount of driver and device tree changes.
Additionally there is a big rework of how pwm lowlevel drivers are
registered to prepare adding character device support.
Thanks to Dharma Balasubiramani, Dong Aisheng, Duje Mihanović, Jerome
Brunet, Raag Jadav and Rafał Miłecki for their contributions. And
sorry for those who still need some patience because I didn't manage
to empty my review queue"
