[Summary]
When the monitor ONLY is connected to the WD19 (DP port) and WD19 is connected to the type c port than boot the machine, the monitor shows no video output after loaded i915.
[Reproduce Steps]
1. connect power cable of WD19
2. connect DP cable from monitor to WD19
3. connect power cable to target system.
4. connect type c cable from WD19 to target system
5. boot up
[Results]
Expected: video output as there is only one monitor connected.
Actual: No video output.

[SRU Justification]
[Impact]
On platforms supported DP tunneling over USB 3.2 or so, a Retimer is
required on the host side to cover insertion loss. On such platforms the
rtimer firmware maybe configured to use LTTPR (Link Training Tunable PHY
Repeater) non-transparent mode only, which is only supported in drm-tip
currently. Without LTTPR support, link training may fail with following
error messages depending on the data path configuration:
i915 0000:00:02.0: [drm] *ERROR* Link Training Unsuccessful
i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun
[Fix]
Patchset https://www.spinics.net/lists/intel-gfx/msg248700.html
("drm/i915: Add support for LTTPR non-transparent link training mode")
is required to fix this issue. It has been landed to drm-tip and will
only included to mainline in v5.11.
Patchset https://patchwork.freedesktop.org/series/76993/ ("Plumb crtc
state to link training code") is included for link training functions
prototype changes.
[Test Case]
On Dell OptiPlex and WD19 docking station, use following steps to verify:
1. disconnect WD19 from OptiPlex, disconnect OptiPlex's power
2. attach OptiPlex's power cord
3. attach WD19's power cord
4. attach DP to WD19
5. attach WD19 to OptiPlex
6. boot up and check if boot to GUI directly
7. `dmesg` and check if aforementioned DRM link training error appears
[Regression Potential]
The second patchset pulled for dependency doesn't have too much
effective changes but refactoring some translation functions, so very
unlikely to have regressions.
For the major part, LTTPR support, when LTTPR is either not detected or
not supported, it will fall back to use transparent mode as it was.
Otherwise, DP Standard recommends to use LTTPR non-transparent mode for
link training, so this should be the right way to have best hardware
support.
