I made some tests and unfortunately there are some problems. Note: i made these tests picking some patches from omap3isp-yuv branch and applying to igep 3.1.0rc9 kernel (more or less like mainline + some bsp patches) so maybe i made some mistakes (the tvp5150 driver is patched too), but due to the nature of the problems i don't think this is the case. Javier patches v1: i can grab frames with yavta but i get only garbage. Javier patches v2: i cannot grab frames with yavta (it hangs). I see only 2 interrupts on the isp, then stops. I compared Javier-v2 registers setup with Deepthy's patches and there are some differences. Moreover i remember that in Deepthy patches vd1 interrupt was not used (and in fact i had the same yavta-hanging problem before, and Deepthy patches solved it). I think Javier-v1 patches didn't hang the isp because they changed vd0/vd1 logic too, so maybe there were only some wrong isp registers but the logic was correct. Now i wonder if it could be easier/better to port Deepthy patches first and then add Javier fixes...
