Public bug reported: [Impact] DP tunneling over USB4 requires additional work in the AMD GPU driver that isn't present in 5.14 or 5.15. The code will be submitted during the 5.16 kernel cycle and will need to be backported into 5.14 OEM kernel to support any programs that need it.
[Fix] Cherry-pick/backport 30 commits from 5.16 to 5.15.
