Could you please double-check that ? I'd like to be sure, not just believe :-)

In that case the OMAP3 ISP driver should set the v4l2_pix_format::field to 
V4L2_FIELD_INTERLACED in the format-related ioctl when an interlaced format is 
used. I suppose this could be added later - Sakari, any opinion ?
