The latest OMAP Camera-ISP code is hosted by Sakari's gitorious repository here:

	http://www.gitorious.org/omap3camera/

But his repository is currently based on this commit in linux-omap:

commit f6ea2bbc8d4346c3a263ed86a92435d67f652809
Author: Roger Quadros <ext-roger.quadros@xxxxxxxxx>
Date:   Thu May 14 13:48:27 2009 -0700

    RX51: Remove multiple definition of MACH_NOKIA_RX51 in Kconfig
    
    This patch prevents "Nokia RX-51 board" from being shown twice in
    'System Type' within Menuconfig.
    
    Signed-off-by: Roger Quadros <ext-roger.quadros@xxxxxxxxx>
    Signed-off-by: Tony Lindgren <tony@xxxxxxxxxxx>

Which is somewhere around v2.6.30-rc5 kernel.

I'm currently trying to rebase this code on top of latest Kevin Hilman's linux-omap-pm Power Management branch, and I'll be publishing it here:

	http://dev.omapzoom.org/?p=saaguirre/linux-omap-camera.git;a=shortlog;h=refs/heads/devel

NOTE: I'm trying to put some sensor drivers there aswell for my 3430SDP/Zoom1 (and coming soon also for Zoom2), but I'm still trying to make it work.

The other gitorious repository was a first try to do that with an older ISP development codebase, but as I had better control under the new dev.omapzoom.org tree, I'm dropping the gitorious one.

There's a version of the IOMMU already merged in mainline for 2.6.30 stable AFAIK, so this dependency should be no more in latest kernel.

In the works...

Thanks for the interest!
