Hello,

here comes the promised v2 of this series. Implicit v1 is available at
https://lore.kernel.org/dri-devel/20230109204758.610400-1-u.kleine-koenig@pengutronix.de
.

Changes since (implicit) v1 all due to feedback by Daniel Thompson:

 - Update changelogs
 - Still disable PWM if there is an enable gpio or a regulator

Best regards
Uwe

  backlight: pwm_bl: Configure pwm only once per backlight toggle
  backlight: pwm_bl: Don't rely on a disabled PWM emiting inactive state
