Merge tag 'pwm/for-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding: "Various changes and minor fixes across a couple of drivers" * tag 'pwm/for-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: pwm: stm32: Pass breakinput instead of its values pwm: stm32: Remove clutter from ternary operator pwm: stm32: Validate breakinput data from DT pwm: Update comment on struct pwm_ops::apply pwm: sun4i: Fix incorrect calculation of duty_cycle/period pwm: stm32: Add power management support pwm: stm32: Split breakinput apply routine to ease PM support dt-bindings: pwm-stm32: Document pinctrl sleep state pwm: sun4i: Drop redundant assignment to variable pval dt-bindings: pwm: mediatek: Remove gratuitous compatible string for MT7629
