The best solution would be to add mt9p031 support to the mt9t001 driver. If 
that's too difficult to start with, you can copy mt9t001 to mt9p031 and modify 
the driver as needed and merge the two drivers when you will be satisfied with 
the result.

The omap34xxcam.ko and isp-mod.ko modules have been merged into a single 
omap3-isp.ko module. All the driver code is now in drivers/media/video/isp.
