Greetings, This series attempts to add support for endpoints (in the DT sense) whose drivers only have a drm_bridge interface, unlike the tda998x, which uses the component framework and provides all of drm_encoder, drm_bridge, drm_connector.
1 & 2 should be fairly non-contentious, and I believe are valuable enough on their own as they remove some pointer chasing and a few allocations at the top level of komeda. 3 is the meat of this series, where I add the drm_bridge endpoint code. This was tested with ti_tfp410 on the back end of a D71. I've tagged it with an RFC since I drew inspiration from tilcdc, which does similar shenanigans to detect tda998x vs non-tda998x, and is hence a precedent for including similar handling, but I wasn't sure if there's a more well established pattern. Note that I opted not to remove the previous way of doing things for tda998x, even though it could work with the drm_bridge handling directly, since AFAIUI, device links haven't been implemented for drm_bridge (see [1] for an attempt at doing that that never landed, and I'm not aware of any refcounting having been added since), and therefore getting a drm_bridge driver rmmod'ed while in use would be Bad(tm).
