That patch just got merged in the media tree a few days ago,

9f7983bdc4925ae2 ("media: rcar-csi2: Propagate the FLD signal for NTSC and PAL")

I'm not sure which tree this patch is developed on but Steve Longerbeam
posted a RFC which IMHO had the fields inverted, there was a discussion
in his thread [1] where I tried to get to the bottom of the issue. My
conclusions there might be wrong due to the issues addressed in this
patch.

Michael: Did you have Steve's patch in your tree when testing this?
