Hi Hans,

the problem I see with the v4l2-framework in this case is that in its current
state it does not allow to exchange information regarding the bus parameters
between the sub device and the controller.

It seems the soc-camera framework is a better choice here, but to make it work
with the saa7121 one would first have to implement support for video output.

What do you recommend?
