[PATCH 6/6] arm64: dts: freescale: imx8mp-verdin: Add Mezzanine with Toradex Display 10.1" LVDS V2

[Leonardo Costa <leoreis.costa@gmail.com>]

From: Leonardo Costa <leonardo.costa@toradex.com>

Add a device tree overlay enabling the Toradex Capacitive Touch Display
10.1" LVDS V2 on the Verdin Development Board with Verdin iMX8M Plus
Mezzanine expansion board. The panel connects via the i.MX8M Plus LCDIF
on the Mezzanine LVDS interface (J10). The panel is an Opto Logic
SCX1001511GGC49 10.1" WXGA TFT LCD LVDS and the touch input is provided
by an ILITEK ILI251x capacitive touch controller.
