I would like to ask your use-case for this. I'm trying to make up the courage to move Gen2 inline with Gen3, that is move Gen2 to use the media graph interface to allow it more complex use-cases, including controlling parameters on the subdevice level. So I'm curious if this solve a particular problem for you or if it's done "just" for completeness. If it solves a real problem then I think we should move a head with a v2 (with the small comment below fixed) if not I would like to try and reduce the non media graph usage of the API as much as possible.
I believe parallel camera - such as ov5642 - connected to Kingfisher's parallel interface still has to be controlled over v4l operations on vin device. And, to control frame rate of such cameras [which is the usecase we have here at Cogent], the operations that this patch adds are requied.
Please use &vin->vdev instead of video_devdata(file).
Preparing v2 now. Nikita
