[PATCH v2 3/7] ARM: dts: imx6q-apalis: Add Toradex Capacitive Touch Display 10.1" LVDS

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@xxxxxxxxxxx>

Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
LVDS connected via the Apalis iMX6 LDB.

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.

Remove the panel-lvds node from the Apalis iMX6 dtsi, as it is an
external component that does not exist at the SoM level.

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.
