As Sergio noted, this is a tree for N900. The main point for the tree, however, is the OMAP 3 ISP driver, which can be tested on N900 as the tree also contains N900 sensor, lens and flash drivers. > Ultimately I want to get raw sensor data to memory.

Go with v4l2_subdev instead. If you have a sensor driver to write, the et8ek8 driver in the omap3camera tree can be used as an example on what ops the sensor driver should implement.

Can you also clarify for me the difference > between omap3camera and your linux-omap-camera > (http://dev.omapzoom.org/?p=saaguirre/linux-omap-camera.git;a=summary) > repositories? No problem. The difference is that, in my 'omap-devel' branch, you'll find: 1. Latest linux-omap master. 2. Some yet unmerged OMAP Zoom3 patches (Touchscreen, NEC LCD panel) 3. Some patches to support Beagleboard xM (OMAP3730) 4. Merged Sakari's 'devel' branch. 5. Some omap3 camera driver unmerged "legacy nodes" removal patches from Laurent Pinchart. 6. Some patches to add support for different RAW Patterns, which I'm still working on. 7. Sony IMX046 8MP CSI-2 Sensor driver, present in Zoom3. 8. LV8093 Lens actuator driver, present on Zoom3 and in tandem with IMX046 sensor > > I assume this development has mainly happened on the "board-rx51*" > platform? Yeah, Sakari and Laurent maintain the rx51 (a.k.a. Nokia N900) camera support. > > Ultimately I want to get raw sensor data to memory. Do you foresee any > problems doing that with the current state of omap3camera? It shouldn't be a problem, as soon as you configure the pipeline adequately. Please see this Media controller testapp, maintained by Laurent Pinchart, for help on how to do that: http://git.ideasonboard.org/?p=media-ctl.git;a=summary Might I be > better off going with a kernel with v4l2_int_device at first? I won't recommend that. You probably noticed that my tree still keeps some branches with support for that old driver, but it was for some maintenance support for a code mainline for Texas Instruments. I'll definitely recommend to stick with the latest code, and most preferably base your work on Sakari's tree (i.e. gitorious.org/omap3camera tree), so we can all reference to a standard codebase. I appreciate your interest in contributing with the camera driver development, and definitely looking forward for any patches you may want to share with us.

Can you also clarify for me the difference between omap3camera and your linux-omap-camera (http://dev.omapzoom.org/?p=saaguirre/linux-omap-camera.git;a=summary) repositories?

This is because devel branch keeps a detailed development history since we started working on the camera driver.

You should preferably send the patches to linux-media (at) vger.kernel.org mailing with cc to Sakari Ailus and Laurent Pinchart. So far we have been keeping patch review internally, because we didn't want to pollute the mailing list with patches to unsubmitted code.
