Merge tag 'pwm/for-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding: "There's quite a few changes this time around. Most of these are fixes and cleanups, but there's also new chip support for some drivers and a bit of rework" * tag 'pwm/for-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (33 commits) pwm: pca9685: Fix PWM/GPIO inter-operation pwm: Make pwm_apply_state_debug() static pwm: meson: Remove redundant assignment to variable fin_freq pwm: jz4740: Allow selection of PWM channels 0 and 1 pwm: jz4740: Obtain regmap from parent node pwm: jz4740: Improve algorithm of clock calculation pwm: jz4740: Use clocks from TCU driver pwm: sun4i: Remove redundant needs_delay pwm: omap-dmtimer: Implement .apply callback pwm: omap-dmtimer: Do not disable PWM before changing period/duty_cycle pwm: omap-dmtimer: Fix PWM enabling sequence pwm: omap-dmtimer: Update description for PWM OMAP DM timer pwm: omap-dmtimer: Drop unused header file pwm: renesas-tpu: Drop confusing registered message pwm: renesas-tpu: Fix late Runtime PM enablement pwm: rcar: Fix late Runtime PM enablement dt-bindings: pwm: renesas-tpu: Document more R-Car Gen2 support pwm: meson: Fix confusing indentation pwm: pca9685: Use gpio core provided macro GPIO_LINE_DIRECTION_OUT pwm: pca9685: Replace CONFIG_PM with __maybe_unused ...
