Maybe, how can we help too ? Hi Jean-Michel, I did post a v4l2 video capture driver for i.MX6 to linux-media. The main complaint from Philip at Pengutronix is that it does not support the media device framework. The customer I am currently working for has no real interest in the media controller API, and the driver I posted has all the features they require, so any work I do to add that support to the driver would have to be in my spare time, and I don't have much. If our customer were to request and fund media control support, that would be ideal, but as it is I can only spend limited time on it. So if you are interested in helping out in the media device effort I can send what I have so far. I have not provided any patches to i.MX6 DRM/KMS drivers. We have developed new features (overlay plane global/local alpha, hardware gamma correction, color-keying, and others) for for that component but haven't posted them yet.
