Hi JM, staging capture driver now compiles at
git@github.com:slongerbeam/mediatree.git, mx6-camera-staging
branch.

It is lightly tested on sabrelite quad (with parallel ov5642), sabreauto quad
(with adv7180 and NTSC/PAL sources), and sabresd quad (with MIPI CSI-2
ov5640).

I have not yet made most of the suggested changes from my version 1 posting
a couple months ago, so for the most part it is in the same state. Still in the process
of making those suggested changes.
