Bug description:
[Impact]
Some OEM platforms swap DP connections on the Rembrandt-R, which causes
improper eDP behavior. The following issues will occur in these designs:
- Fn key failed to control brightness
- eDP remains black screen during S0i3 cycle
AMD has fixed these issues, but it requires both a kernel patch and an
updated DMCUB microcode.
[Test Plan]
Validate brightness control works.
Validate that PSR works.
Validate that eDP works after suspend/resume.
Validate that external display works.
Run above test plan on Rembrandt or Rembrandt-R system with swapped DP
as well as one without swapped DP.
[Where problems can occur]
The code and DMCUB microcode are localized to AMD Rembrandt/Rembrandt-R
systems. Issues would occur specifically on these designs, which is why they
should be tested.
