Host's single lane training algorithm in kernel (intel_dp_is_reversed) appears to confuse the re-driver's auto training algorithm. If however its manually configured the algorithm succeeds. NOTE, this does present risk on the DPsrc (re-driver) to DPsink (external monitor) side as voltage levels & pre-emphasis will NOT be adjusted. This may be acceptable in the short-term while determining if additional functionality needs to be added on host side to account for re-driver's presence Signed-off-by: Todd Broch <tbroch@chromium.org> BRANCH=none BUG=chrome-os-partner:35153 TEST=manual, plankton drives 4K monitor in both polarities Change-Id: I83ea80c44d36ad1afad56528c80ec5b8a138b5be Reviewed-on: https://chromium-review.googlesource.com/263138 Reviewed-by: Alec Berg <alecaberg@chromium.org> Commit-Queue: Todd Broch <tbroch@chromium.org> Tested-by: Todd Broch <tbroch@chromium.org>
