It would be nice to have a list of which drivers are affected and to
what degree (ie. if only minor things need to be changed or if the whole
driver is affected).
Could you try to create such a list?

For example, my MXB driver uses video_decoder.h to drive the saa7111
video decoder. What changes are necessary here?
IMO video_decoder can be dropped completely, because I know that the MXB
has a saa7111 and I know which features are used.
Will there be a new dedicated saa7111 driver that understands v4l2
Or should I got and implement the few necessary i2c command sequences
directly? (probably not)

Thanks for the initiative.
