.... return drm_bridge_attach(encoder, bridge, NULL, 0); ....
The above code-snippet tells that the display-driver rely on the bridge to create the connector. Could this by any chance be updated to the new way where the display driver creates the connector - and thus passing DRM_BRIDGE_ATTACH_NO_CONNECTOR as the flags argument?
What bridges would be relevant? To check that the reelvant bridges are already ported.
