            Bug ID: 217636
           Summary: Commit edcfed8671 disables previously supported video
                    resolutions (on AMD Rembrandt)
           Product: Drivers
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: saverio.pub2@gmail.com
        Regression: No

I have a laptop with an AMD Rembrandt APU (6800U).

The display has a native resolution of 2880x1800, however, via
`~/.config/monitors.xml`, I set it 1920x1200.

After the upgrade to the kernel v6.3.9, the resolution 1920x1200 is not allowed
anymore, and on login, I see a brief popup with an error.

After bisection, i've isolated the culprit to commit `edcfed8671`
("drm/amd/display: edp do not add non-edid timings").

The revert of that patch is already on it's way to Linus.
