[PATCH v2] drm/i915: Refine eDP aux backlight enable/disable sequence

[Lee Shawn C]

Modify aux backlight enable/disable sequence just like what we
did for genernal eDP panel.
1. Setup PWM freq and brightness level before enable display backlight.
2. Set PWM to 0 after backlight enable was off.

v2: Code structure was changed. Modify this patch to align the latest.

It took me a while to realize why we do this in this order.

eDP v1.4b says about DPCD addresses 00722h-00723h
i.e. EDP_BACKLIGHT_BRIGHTNESS MSB and LSB:

"""
Writes are ignored if:

[...]

- BACKLIGHT_ENABLE bit in the EDP_DISPLAY_CONTROL register (DPCD Address
  00720h, bit 0) is cleared to 0"
"""

i.e. per the spec this change makes the brightness updates no-ops.

Do you have a panel where this patch makes a difference?

BR,
Jani.

What you say is correct. According to spec, write EDP_BACKLIGHT_BRIGHTNESS does not affect
if BACKLIGHT_ENABLE already be off.

Backlight enable always turn off before stop PWM output when used general eDP backlight (from SOC) control.
But AUX backlight control is a little different. I will update this patch and remove "Set PWM to 0".

AFAICT the only thing you can do, really, is calling
intel_dp_aux_set_backlight(old_conn_state, 0); *before*
set_aux_backlight_enable(enc_to_intel_dp(old_conn_state->best_encoder),
false); in intel_dp_aux_disable_backlight().

Jani.

Please think it through again. The same applies here. The brightness
change before enable is ignored according to eDP spec.

This is what the problem we see on a new eDP panel from customer. TCON did not turn backlight on successful.
After sawp the sequence, backlight works well as expected. 

In the other words. Looks like this TCON backlight enable flow violate eDP spec. What do you think?

[PATCH v2] drm/i915: Refine eDP aux backlight enable/disable sequence

[Lee Shawn C]

Modify aux backlight enable/disable sequence just like what we
did for genernal eDP panel. Setup PWM freq and brightness level
before enable display backlight.

v2: According to spec, it is not necessary to set PWM to 0 if
    backlight enable already off. Remove intel_dp_aux_set_backlight to 0.
