Welcome to the world of the ov7670! My conclusion, after working with this sensor, is that is consists of something like 150 analog tweakers disguised as digital registers. Everything interacts with everything else, many of the settings are completely undocumented, and that's not to mention the weird multiplexor at 0x79. It's hard to make this thing work if you don't have a blessed set of settings from OmniVision. > Clearly this driver shares considerable portions of code with > Jonathan Corbet's driver (in tree).

As Hans noted, he's already put quite a bit of work into generalizing the ov7670 driver; I think it would be best to work with him to get a driver that works for everybody.
