In order to support that, we need drm bridges to fully take part in the atomic state validation process, which requires adding a drm_bridge_state and a new drm_bridge_funcs.atomic_check() hook. Once those basic building blocks are in place, we can add new hooks to allow bus format negotiation (those are called just before ->atomic_check()). The bus format selection is done at runtime by testing all possible combinations across the whole bridge chain until one is reported to work. No fundamental changes in this v9. Just a few clarifications in the bridge atomic hooks/helpers doc, and we also moved the drm_atomic_private_obj_init() call back to drm_bridge_attach(). This patch series is also available here [1].
