Comments are highly appreciated. The tree is a 2.6.37 that already contain Deepthy patch. I rebased my changes on top of that to correctly support both BT656 an non-BT656 video data processing.

Capturing YUV frames and looking at them I realized that there does exist a pattern, the sequence 2 frames correct and 3 frames with interlacing effects always repeats. Hope it helps.
