OMAP: CAM ISP: looking for a good start point

OMAP: CAM ISP: looking for a good start point

[Stephan Linz]

Hi Sergio, Hi Sakari,
Hello OMAP devel team,

as far as I can see you are working on a V4L2 driver set for the OMAP3 Camera 
Interface Subsystem (ISP) at this time. Just I'm looking for a good start 
point to integrate your ongoing work in my own devel git tree and further 
expand it with my own sensor and board specific code. But, there are two 
different git trees hosted by gitorious:
  * http://www.gitorious.org/omap3-linux-camera-driver
  * http://www.gitorious.org/omap3camera/

Which of them is the latest and active development tree?

Are there any thirt party dependencies to other kernel development? I know the 
IOMMU patch set by Hiroshi Doyu (http://lwn.net/Articles/321692/), it is all?

Is there a short README or TODO list (status)?



Thank you and 
Best Regards
Stephan Linz

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@nokia.com>
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@nokia.com>
    Signed-off-by: Tony Lindgren <tony@atomide.com>

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!
