Heh. Basically anything is easier to develop for than n900 :-(.

Ok, for real testing, Ivaylo's camera patchset is useful, so that you
have picture to work with, plus your subdevs for omap3 patchset (which
needs a forward port).

I have patches against v4.7, if you are interested.

I guess subdevs for omap3 should be merged at this point. Do you have
any plans to do that, or should I take a look?

Best regards,
