I grepped dts trees a bit... where is omap3isp currently used?
Anything besides N9 and N950?

Does the capture mode currently work for you?

Because as far as I can tell, formatter is disabled, so video is in
wrong format for the userspace.

So something like patch below is needed; (of course after adjusting
the comment etc.)

Thanks,

    omap3isp: fix VP2SDR bit so capture (not preview) works
    
    This is neccessary for capture (not preview) to work properly on
    N900. Why is unknown.
