Hi Gary,

I'm currently on the process to rebase and verify all this code on 3430SDP, Zoom1 and soon Zoom2.

Here you can find my progress:

http://dev.omapzoom.org/?p=saaguirre/linux-omap-camera.git;a=summary

Check devel branch, which contains all latest Sakari's tree patches (http://gitorious.org/omap3camera) rebased on top of latest Kevin's l-o PM tree, plus the patches, which are still in works, to make the above mentioned platforms to work.

I'm first trying to make 3430SDP work, don't have a Zoom1/Zoom2 handy right now...

My gitorious tree will eventually disappear, as I can work better with this new one.

I'll consolidate some patches when this sensor code is ready, and will CC you if interested.

Regards,
Sergio
