[PATCH 4/5] ARM: dts: imx6dl-colibri: Add Toradex Resistive Touch Display 7" Parallel

[Antoine Gouby]

From: Antoine Gouby <antoine.gouby@xxxxxxxxxxx>

Add a device tree overlay for the Resistive Touch Display 7" Parallel
on the Colibri iMX6 parallel RGB LCD interface.

The panel is a LogicTechno LT161010-2NHR 7" WVGA TFT Transmissive LCD
with a resistive touch, handled by the touch controller on the module.

The overlay is also combined with the Colibri iMX6 V1.2 Evaluation
Board v3 device tree to provide a ready-to-use DTB.
