With only a single display pipeline and primary plane, udl is perfect for simple-pipe helpers. Patches 1 to 3 do the convertion. This enables atomic modesetting for udl devices. Patches 4 to 7 clean up handling of color depth and framebuffers. With universal planes that come with simple pipe, display updates can be implemented with DRM's damage handlers. The primary plane's formats array allows to export the correct preferred color depth. The original value was choosen for maximum compatibility, but did not represent the device's capability. The patchset has been tested by running the fb console, X11 and Weston on a DisplayLink adapter.
