This patch looks good in itself, but I would like to see a tested by
tag. At the very least testing for regression in single-link LVDS but
ideally some third party verification of this patch.

Robert,
I do not have the hardware to test this feature. Sorry for the late
response.

Jiri: Are you able to test this patch?

Vinay: Could you supply a R-b tag, if you feel that it is warranted?

Actually, this patch is based on testing with a real HW with dual-link LVDS
display (full HD) and it also matches with a datasheet. Without this fix it
does not work at all.

Excellent.

Jiri, can you add your Tested-by tag to this patch?
