Merge tag 'pwm/for-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding: "This contains a bunch of cleanups and simplifications across the board, as well as a number of small fixes. Perhaps the most notable change here is the addition of an API that allows PWMs to be used in atomic contexts, which is useful when time- critical operations are involved, such as using a PWM to generate IR signals. Finally, I have decided to step down as PWM subsystem maintainer. Due to other responsibilities I have lately not been able to find the time that the subsystem deserves and Uwe, who has been helping out a lot for the past few years and has many things planned for the future, has kindly volunteered to take over. I have no doubt that he will be a suitable replacement" * tag 'pwm/for-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (44 commits) MAINTAINERS: pwm: Thierry steps down, Uwe takes over pwm: linux/pwm.h: fix Excess kernel-doc description warning pwm: Add pwm_apply_state() compatibility stub pwm: cros-ec: Drop documentation for dropped struct member pwm: Drop two unused API functions pwm: lpc18xx-sct: Don't modify the cached period of other PWM outputs pwm: meson: Simplify using dev_err_probe() pwm: stmpe: Silence duplicate error messages pwm: Reduce number of pointer dereferences in pwm_device_request() pwm: crc: Use consistent variable naming for driver data pwm: omap-dmtimer: Drop locking dt-bindings: pwm: ti,pwm-omap-dmtimer: Update binding for yaml media: pwm-ir-tx: Trigger edges from hrtimer interrupt context pwm: bcm2835: Allow PWM driver to be used in atomic context pwm: Make it possible to apply PWM changes in atomic context pwm: renesas: Remove unused include pwm: Replace ENOTSUPP with EOPNOTSUPP pwm: Rename pwm_apply_state() to pwm_apply_might_sleep() pwm: Stop referencing pwm->chip pwm: Update kernel doc for struct pwm_chip ...
