Merge tag 'pwm/for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding: "Besides one new driver being added for the PWM controller found in various Spreadtrum SoCs, this series of changes brings a slew of, mostly minor, fixes and cleanups for existing drivers, as well as some enhancements to the core code. Lastly, Uwe is added to the PWM subsystem entry of the MAINTAINERS file, making official his role as a reviewer" * tag 'pwm/for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (34 commits) MAINTAINERS: Add myself as reviewer for the PWM subsystem MAINTAINERS: Add patchwork link for PWM entry MAINTAINERS: Add a selection of PWM related keywords to the PWM entry pwm: mediatek: Add MT7629 compatible string dt-bindings: pwm: Update bindings for MT7629 SoC pwm: mediatek: Update license and switch to SPDX tag pwm: mediatek: Use pwm_mediatek as common prefix pwm: mediatek: Allocate the clks array dynamically pwm: mediatek: Remove the has_clks field pwm: mediatek: Drop the check for of_device_get_match_data() pwm: atmel: Consolidate driver data initialization pwm: atmel: Remove unneeded check for match data pwm: atmel: Remove platform_device_id and use only dt bindings pwm: stm32-lp: Add check in case requested period cannot be achieved pwm: Ensure pwm_apply_state() doesn't modify the state argument pwm: fsl-ftm: Don't update the state for the caller of pwm_apply_state() pwm: sun4i: Don't update the state for the caller of pwm_apply_state() pwm: rockchip: Don't update the state for the caller of pwm_apply_state() pwm: Let pwm_get_state() return the last implemented state pwm: Introduce local struct pwm_chip in pwm_apply_state() ...
