[PATCH v2 0/7] imx-drm: ipuv3-crtc: Implement mode_fixup

[Liu Ying]

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.
