Merge tag 'pwm/for-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding:
"This adds support for the PWM controller found on Toshiba Visconti
SoCs and converts a couple of drivers to the atomic API.
There's also a bunch of cleanups and minor fixes across the board"
