[PATCH v3] drm: tilcdc: add a da850-specific compatible string
From: Bartosz Golaszewski
Date: Mon Oct 03 2016 - 11:45:55 EST
Due to some potential tweaks for the da850 LCDC (for example: the
required memory bandwith settings) we need a separate compatible
for the IP present on the da850 boards.

v1 -> v2:
- added the new compatible to the bindings documentation

- made the documentation more detailed
