This patch is needed to have display working on many Exynos boards.

$subject enables the config option for the ps8622/ps8625 eDP/LVDS
bridge driver but this has not landed in mainline yet. Ajay will
re-spin a new revision of his series that adds this driver though,
after addressing some issues pointed out on a previous version.

The Kconfig symbol name (DRM_PS8622) won't change though so maybe is
not crazy to pick the patch as is since CONFIG_DRM_PS8622 will have to
be enabled later when the bridge driver lands. Or do you want me to
re-spin $subject removing that option?

Best regards,
Javier
