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.

This patchset implements ->mode_fixup() in the imx ipuv3-crtc driver,
using a new support function ipu_di_adjust_videomode(). This new
function needs to be subsystem independent, so it accepts a video
mode as a 'struct videomode'. Hence ipu-crtc ->mode_fixup() needs
another support function to convert a drm_display_mode to a videomode
before passing the mode to ipu_di_adjust_videomode() for fixup.

Also some related code cleanup: 'struct ipu_di_signal_cfg' should
use 'struct videomode' for mode timings.

Alright, I have applied the series with
s/videomode_from_drm_display_mode/drm_display_mode_to_videomode/

thanks
Philipp
