True. Couldn't this be a library that handles the code difference between
soc-camera platform-data bits and normal subdev?

Even better: couldn't this code be handled by soc_camera core and just use
subdev interface for both cases?

After finishing the patch, please ping me. I have here an OLPC with ov7670 where
I can test if the new code doesn't break the cafe_ccic driver. You'll probably
need to touch on it, as it will need to use the new mediabus API to talk with
