I want to make it clear that I don't want to claim any privilege in getting patches merged first. I am however worried that, without an easy way to test DSI support, and without enough time to focus on it, I would break whatever would be merged now in future reworks. I would thus like to find out how to collaborate on this task, hopefully to move towards usage of drm_bridge and drm_panel for DSI-based pipelines. -- Regards, Laurent Pinchart
