[PATCH v1 3/3] ARM: dts: imx7d-colibri-emmc: Add Toradex Capacitive Touch Display 10" LVDS

[Francesco Dolcini]

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

Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
LVDS connected via a DPI to LVDS on Iris carrier board. The panel is a
LogicTechno LT170410-2WHC 10.1" WXGA IPS LCD and the touch input is
provided by an Atmel MaxTouch capacitive touch controller.

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