Merge tag 'pwm/for-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "This set is mostly small fixes and cleanups, so more of a janitorial
  update for this cycle"

* tag 'pwm/for-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm:
  pwm: vt8500: Rename pwm_busy_wait() to make it obviously driver-specific
  dt-bindings: pwm: tpu: Add R-Car M3-W+ device tree bindings
  dt-bindings: pwm: tpu: Add R-Car V3U device tree bindings
  pwm: pwm-samsung: Trigger manual update when disabling PWM
  pwm: visconti: Simplify using devm_pwmchip_add()
  pwm: samsung: Describe driver in Kconfig
  pwm: Make it explicit that pwm_apply_state() might sleep
  pwm: Add might_sleep() annotations for !CONFIG_PWM API functions
  pwm: atmel: Drop unused header
