To support interlaced scan with planar formats, cpmem SLUV must
be programmed with the correct chroma line stride. For full and
partial planar 4:2:2 (YUV422P, NV16), chroma line stride must
be doubled. For full and partial planar 4:2:0 (YUV420, YVU420, NV12),
chroma line stride must _not_ be doubled, since a single chroma line
is shared by two luma lines.

Ok thanks.
Hans, for v5 I will just include the two IPU patches as before. As Philipp
stated, he is OK with merging them to the media tree (after his ack of
course), along with the rest of the patches in this series.
