[PATCH v1 1/3] ARM: dts: imx7d-colibri-emmc: Add Toradex Capacitive Touch Display 7" Parallel

[Francesco Dolcini <francesco@dolcini.it>]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add a device tree overlay for the Capacitive Touch Display 7" Parallel
on the Colibri iMX7 parallel RGB LCD interface.

The panel is a LogicTechno LT161010-2NHC 7" WVGA TFT Transmissive LCD
and the touch input is provided by an Atmel MaxTouch capacitive touch
controller.

The touch controller is connected to the Toradex 10-way Capacitive Touch
Interface connector available on Iris v2 and Aster carrier boards.

The overlay is also combined with the Iris v2 and Aster carrier board
device tree to provide a ready-to-use DTB.
