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.
