Subject: [PATCH 0/5] pwm: rcar: Add support "atomic" API and workaround
Date: Fri,  7 Dec 2018 17:29:28 +0900	[thread overview]
Message-ID: <1544171373-29618-1-git-send-email-yoshihiro.shimoda.uh@renesas.com> (raw)

This patch adds support for PWM "atomic" API.

This patch also adds a workaround to output "pseudo" low level.
Otherwise, the PWM backlight driver doesn't work correctly, especially
it cannot output maximum brightness actually.

Yoshihiro Shimoda (5):
  pwm: rcar: add rcar_pwm_calc_counter() to calculate PWMCNT value only
  pwm: rcar: Add support "atomic" API
  pwm: rcar: Use "atomic" API on rcar_pwm_resume()
  pwm: rcar: remove legacy APIs
  pwm: rcar: add workaround to output "pseudo" low level
