Hi,
So here's the patchset for OMAP 3 ISP and camera drivers plus the
associated V4L changes. Sergio Aguirre has been posting a related
patchset earlier, containing also sensor and lens driver used on SDP.
This patchset is agains the linux-omap tree:
<URL:http://www.muru.com/linux/omap/README_OMAP_GIT>
So I and Sergio have synchronised our versions of the ISP and camera
drivers and this is the end result. There is still a lot of work to do,
though. You can find some comments in individual patch descriptions. If
the todo list for a patch is empty it doesn't mean there wouldn't be
anything left to do. ;)
There's at least one major change to Sergio Aguirre's earlier patches
which is that the ISP driver now uses the IOMMU from Hiroshi Doyu.
Hiroshi is away for some time now so there are just some hacks on top of
Hiroshi's older iommu patches to use with current linux-omap.
This patchset does not contain the resizer or preview wrappers from TI
but they have been left intentionally out. A proper interface (V4L)
should be used for those and the camera driver should be somehow
involved --- the wrappers are just duplicating much of the camera
driver's functionality.
I don't have any sensor or lens drivers to publish at this time.
This patchset should work with the SDP and OMAPZoom boards although you
need the associated sensor drivers + the board code from Sergio Aguirre
to use it. You'll also need the IOMMU patchset from Hiroshi Doyu.
Everything except the sensor / board stuff is available here:
<URL:http://www.gitorious.org/projects/omap3camera>
In short, on linux-omap:
$ git pull http://git.gitorious.org/omap3camera/mainline.git v4l \
iommu omap3camera base
Hiroshi's original iommu tree is here (branch iommu):
<URL:http://git.gitorious.org/lk/mainline.git>
Some of the camera and ISP driver development history is available, too.
See the first link.
Any feedback is appreciated.
Sincerely,
