Hello Laurent,

I was working on having a functional IOMMU/ISP for 3.14, and had an
issue with an image completely distorted. Comparing with another kernel,
I saw that PRV_HORZ_INFO and PRV_VERT_INFO differed. On the newer
kernel, sph, eph, svl, and slv were all off-by 2, causing my final image
to miss 4 pixels on each line, thus distorting the result.

Your commit 3fdfedaaa7f243f3347084231c64f6c1be0ba131 '[media] omap3isp:
preview: Lower the crop margins' indeed changes PRV_HORZ_INFO and
PRV_VERT_INFO by removing the if() condition. Reverting it made my image
to be valid again.

FYI, my pipeline is:

MT9V032 (SGRBG10 752x480) -> CCDC -> PREVIEW (UYVY 752x480) -> RESIZER
-> out

Regards,

Florian
