Merge tag 'pwm/for-6.12-rc7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux
Pull pwm fix from Uwe Kleine-König:
"Fix period setting in imx-tpm driver and a maintainer update
Erik Schumacher found and fixed a problem in the calculation of the
PWM period setting yielding too long periods. Trevor Gamblin - who
already cared about mainlining the pwm-axi-pwmgen driver - stepped
forward as an additional reviewer.
Thanks to Erik and Trevor"
