Yeah, I know, and I'm sorry for that :(
Lately, I have been busy with some high priority customer specific tasks, and
haven't had time to work on the public tree at all...
The good thing is that I'll be now dedicating on this full time, as This will
eventually become my only task in the future (interact with the community for
enahncemets/fixes in the driver).
One bad thing is that as I don't have a BT656 sensor with me, its near to
impossible for me to develop on that area, so Vaibhav Hiremath in their PSP
releases, is doing that instead. Anyways, I'll be looking forward to make those
changes part of my tree aswell, if Vaibhav is ok with it (as I'm almost
completely sure he is)

Ok, let me explain the currently existing trees, and their connection:
Linux-omap is the "baseline" in which all this code is based, because you
couldn't find everything yet on kernel.org.
Sakari Ailus (from Nokia) and Myself (from TI) we're trying to get the code
accepted on the linux-omap and linux-media lists, so Sakari created a tree
which contains the latest developed driver in Nokia, which is based on an older
internal TI code, and in which I have been helping to fix for acceptance
aswell. You can find that tree here:
http://gitorious.org/omap3camera
But that tree only contains the core OMAP3 Camera-ISP driver, without any
sensor or board specific code, and also it is based on an older kernel (because
is the one in which Sakari tests). So there's when my tree comes to overcome
this things. So I created a tree in gitorious right away:
http://gitorious.org/omap3-linux-camera-driver
And Vaibhav, who was interested in bringing up this code on 3530EVM with an
onboard TV tuner interfaced with BT656 to the camera driver (like it was a
sensor), started his development on top of my gitorious tree.
Later on, Sakari updated his tree with some more code changes, but this time I
could get a more formal tree under the omapzoom server, in which TI has full
control. So instead of updating my gitorious, I decided to better create a new
tree, and pull there the new code coming from Sakari's tree instead. So I
created the tree you're currently looking at:
http://dev.omapzoom.org/?p=saaguirre/linux-omap-camera.git;a=shortlog;h=refs/heads/devel
In which I'm trying to make work my 3430SDP with some camera sensors I have
handy (MT9P012 and OV3640), an OMAP Zoom1 (a.k.a. LDP), and an OMAP Zoom2
(under works still).
So, I hope looks clear for you on how all these trees are related...

The CCDC is capable of saving to memory directly, so you don't specifically
need Preview and resizer all the time.

What I do feel is that the PSP base will fulfill better your immediate needs,
but in the future, as I'm getting aware of Vaibhav changes, I'll be interested
in making them part of my tree aswell, so Vaibhav could avoid rebasing the
BT646 support internally everytime...

Thanks for your interest!
