it appears the same driver is used for all of the omap 3 series. The link below mentions N900 support. http://gitorious.org/omap3camera/pages/Home The link below is to the git repo for the omap3 camera drivers which also contains the n900 driver(RX-51) branch. http://gitorious.org/omap3camera I am not sure about the specific camera sensor for the n900 so I am not sure which modes it operates in(the camera sub system module manual shows different modes for sensors). The mode shouldn't effect what you are looking at doing and the drivers probably answer the question of what mode it operates in. I have seen some camera sensor modules that actually put out JPEG by default and need to be reconfigured to output RAW. Depending on how the drivers are configured(unfortunately i do not have time to have a look and find out atm) changing settings may be as easy as unloading the driver and reloading the driver with parameters. Now the only problem would be how the camera is switch and changes with the driver parameters would effect the other camera(the same input on the ISP is used for both cameras).
