Mario Limonciello 0fb915d64d drm/amd/display: Only enable common modes for eDP and LVDS ... [Why] The main reason common modes are added is for compatibility with clone mode when a laptop is connected to a projector or external monitor. Since commit 978fa2f6d0 ("drm/amd/display: Use scaling for non-native resolutions on eDP") when non-native modes are picked for eDP the GPU scalar will be used. This is because it is inconsistent whether eDP panels have the capability to actually drive non-native resolutions. With panels connected to other connectors this limitation generally doesn't exist as we the EDID will advertise support for a number of resolutions and monitors will use built in scaling hardware. Comparing DC and non-DC code paths the non-DC code path only adds common modes for LVDS and eDP whereas the DC codepath does it for all connector types. In the past there was an experiment done to disable common mode adding for eDP and LVDS from commit 6d396e7ac1 ("drm/amd/display: Disable common modes for LVDS") and commit 7948afb46a ("drm/amd/display: Disable common modes for eDP") but this was reverted in commit a8b79b0918 ("drm/amd: Re-enable common modes for eDP and LVDS") because it caused problems with Xorg. [How] Only add common modes for eDP and LVDS for DC, matching the behavior of non-DC.
