[PATCH 3/4] ARM: mxs: dt: Add the Crystalfontz CFA-10055 device tree

From: Maxime Ripard
Date: Thu Jun 13 2013 - 09:44:02 EST

From: Brian Lilly <brian@xxxxxxxxxxxxxxxx>

The CFA-10055 is yet another breakout board for the CFA-10036, and is
basically a CFA-10037, with the screen and LCD controller found on the
CFA-10049.
