I am now able to register a camera device on the soc_camera bus with
mx3_camera, I had not initialized well the bus_id for my platform
device. After struggling with a few minor hardware bugs, I am now able
to register a MT9T031 camera (actually we have a MT9T001 for testing,
but they are very similar).

So things seem to be working fine. I am testing it with the capture.c
example from v4linux. But the mt9t031 only supports bayer format atm (I
could try to work on it, but first I need to validate our hardware
design by grabbing real images), could someone point me to an easy way
of converting this bayer format to something readable (maybe a raw image
for gimp, that's what I am trying to do now) ?

By the way, Guennadi, if you want me to test something more extensively,
don't hesitate to ask me about it.

Thanks again for your patch.

Val
