ENGR00255371 v4l2 fg overlay:workaround ipu warning
There is annoying ipu warning when doing preview
by using v4l2 fg overlay component:
/unit_tests/mxc_v4l2_overlay.out -iw 320 -ih 240 -ow 1280
-oh 720 -r 0 -fg -t 5
imx-ipuv3 imx-ipuv3.0: IDMAC12's EBA0 is not 8-byte aligned
This warning can be seen only when preview size is bigger
than 1024*1024(ipu device driver split mode is enabled).
After debug, it appears that the unaligned buffer address
is caused by input cropping for left strip, and this
cropping is triggered by the split mode algrithm. The
algrithm is complex, so currently this patch only changes
the input pixel format of the ipu task from UYVY to NV12
to workaround this warning.
