[J][PATCH 00/30] drm/amdgpu: Add USB4 support for DP tunneling

[Timo Aaltonen]

BugLink: https://bugs.launchpad.net/bugs/1951868

This is needed in OEM-5.14, but in order to verify that the upgrade path
has it too, we'd need to first know that it is accepted in jammy.

Most patches were straight cherry-picks, some needed minor conflict fixes,
and patch 11 adds an enum from a huge, otherwise unrelated commit which
we don't want to backport.
