Hardware needs a delay between setting an initial (non-zero) PWM and
enabling the backlight using GPIO. The post-pwm-on-delay-ms specifies
this delay in milli seconds. Hardware also needs a delay between disabing
the backlight using GPIO and setting PWM value to 0. The pwm-off-delay-ms
is this delay in milli seconds.

Looks like this still needs an Ack.
Also, you didn't supply a 0th (cover-letter) patch, so I have no idea
of patch history or your future intentions.
Are there build-time dependencies between them or can each patch be
merged via their respective trees without the fear of merge/build
failure?
