Bug Description
[Impact]
The screen brightness is unable to adjust on BOE panel DPN#R6FD8
[Fix]
AMD provides a patch which is included in v6.8-rc7 to fix this issue
b7cdccc6a849 drm/amd/display: Add monitor patch for specific eDP
To avoid conflicts, pull in 3 other small patches
c4e532f75336 drm/amd/display: Re-add aux intercept disable delay generically for 2+ LTTPRs
923bbfe6c888 drm/amd/display: Clear dpcd_sink_ext_caps if not set
3d71a8726e05 drm/amd/display: Add monitor patch for specific eDP
[Test Case]
1. Boot to OS
2. Adjust the screen brightness via the hotkeys on the keyboard or brightness bar in the setting.
3. The screen brightness should change
[Where problems could occur]
The first commit introduces no functional changes, it merely relocates the delay flag to dc_debug_options and makes some consequent modifications.
The second commit introduce a new flag, but we don't use it.
The third and forth commits add 4 panel IDs which should be pretty safe to include them.
