Bug description:
[Impact]
In Dell platform OLED machine with eDP 1.5, monitor's brightness won't change
when pressing brightness key F6/F7.
[Fix]
Cherry-pick the following patchset which has already landed in linux-next:
https://patchwork.freedesktop.org/series/143910/#rev3
which contains:
5dfc37a6b77b drm/dp: Add eDP 1.5 bit definition
9ee185564425 drm/dp: Increase eDP display control capability size
9535c6a4c61c drm/i915/backlight: Use proper interface based on eDP version
64481497924d drm/i915/backlight: Check Luminance based brightness control for
VESA
3f8a009a794e drm/i915/backlight: Modify function to get VESA brightness in
Nits
b68074efcfcf drm/i915/backlight: Add function to change brightness in nits
for VESA
8d502933ac20 drm/i915/backlight: Setup nits based luminance via VESA
a5efc8dcfe71 drm/i915/backlight: Enable nits based luminance
===============================================================================
Besides, there will be a prerequisite patch needed in order to clean-apply
the above patchset:
6276706f33cc drm/i915/display: convert dp aux backlight to struct
intel_display
So there will be 9 patches in total.
[Test Plan]
1. Boot up the Ubuntu OEM image
2. Wait until the screen shows the desktop
3. Press brightness keys (F6 or F7) and see if the brightness has changed.
[Where problems could occur]
May cause regression on some monitors which use the old brightness-changed
path (PWM path).
