Hi,
It looks that the below commit makes my Hannstar XGA LVDS panel stop working
on the i.MX6DL SabreSD board. Any idea?

imx-drm: encoder prepare/mode_set must use adjusted mode
The encoder ->prepare() and ->mode_set() methods need to use the
hw adjusted mode, not the original mode.

What are this panel timings? The adjustment should increase the vertical
back porch by up to two lines (so it is at least two lines), reducing
the front porch or vsync length by the same amount. Does this panel use
the HSYNC/VSYNC signals embedded in the LVDS stream?
