Hi All,

I'm using the S5PV210 camera IF and capturing BT656 video from a TVP5150
video decoder.

I notice that the capture driver ignores the field interlace flags
reported by the 'sensor' and always uses 'V4L2_FIELD_NONE'.  It also
seems each field ends up in it's own frame, using only half the height.

What would need to be done to store both fields in a single frame, for
example in a V4L2_FIELD_INTERLACE_TB/BT format? 

Cheers,
Mike
