Hi Jean-Michel, Phillip, I've done some work on Philipp's June 12 patchset, converting the CSI driver to a CSI subdev entity, and fixing some issues here and there. This June 12 patchset doesn't appear to be a fully working driver, Phillip correct me if I am wrong. I can post this work as it exists, it is incomplete but compiles. I've also worked out what I think is a workable video pipeline graph for i.MX, suitable for defining the entities, pads, and links. Unfortunately I haven't been able to spend as much time as I'd like on it. The complete driver I posted to the list does have some minor issues mostly suggested by Hans Verkuil (switch to new selection API instead of cropping API for example). It is a full featured driver but it does not implement the media device framework, i.e. user does not have direct control of the video pipeline, rather the driver chooses the pipeline based on the traditional inputs from user (video format and controls). If there is interest I can submit another version of the traditional driver to resolve the issues. But media device is a major rework, so I don't know whether it would make sense to start from the traditional driver and then implement media device on top later, since media device is almost a complete rewrite.
