Uh, I knew that question would come up... =)

So far I've mainly tried the SuperH Mobile CEU driver on a MigoR QVGA
board, which means a sh7722 processor (which includes the CEU) and a
ov7725 camera. I also have a sh7723 board with a ncm03j camera (i
think, no docs), but that combination isn't up an running yet.

As for camera drivers, I'm sorry to say that I've been using hacked-up
out-of-tree drivers. I'd like to add upstream support for both camera
types, but I'm not sure if I have enough time before the merge window
closes for 2.6.27. So I've prioritized the CEU driver so far since
it's easy to reuse.

Regarding the ov7725 driver - there seem to be quite a few
half-fitting candidates out there already. I'm thinking about the
ovcamchip/ code and the ov7670.c driver. I need something for the
soc_camera framework though. What to do? Any recommendations?

Thanks,
