[PATCH V6 2/2] video: drm: exynos: Add device tree support

Hello Stephen Warren,

The binding names that I use in my dts file should match with the
names given in http://lists.freedesktop.org/archives/dri-devel/2012-July/024875.html
right?
I think that is the only thing I have to take care, and as I'm not
using "struct drm_display_mode"  in my driver its my wish whether to
use the helper function or not.
Please clarify me if I miss something.

Best Regards,
Leela Krishna Amudala.
