In commit 8a3b4c17f863 ("drm/msm/dp: employ bridge mechanism for display enable and disable") the DP driver received a drm_bridge instance, which is always attached to the encoder as a root bridge. However it conflicts with the panel_bridge support for eDP panels.
Can you elaborate here? How does it conflict? Could be as simple as "it attaches before the panel bridge can attach to the root" or something like that.
Actually it would be the other way around: panel bridge attaching before the "dp" one. But yes, you got the idea. I'll extend the patch's description.
Change panel_bridge attachment to come after dp_bridge attachment.
