[PATCH 5/7] ARM: dts: imx6q-apalis: Add Toradex Resistive Touch Display 7" Parallel

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@xxxxxxxxxxx>

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

The panel is a LogicTechno LT161010-2NHR 7" WVGA TFT Transmissive LCD
with a resistive touch.

The overlay is also combined with the Apalis iMX6 V1.2 Ixora Carrier
Board V1.2 device tree to provide a ready-to-use DTB.
