This patch adds support for the Ka-Ro electronics GmbH TX6 modules. There are five distinct module types with either i.MX6Q or i.MX6DL and LVDS or LCD display interface and one DTS file for a complete system with an i.MX6DL based TX6 module and a baseboard mounted on the back of a display (imx6dl-tx6dl-comtft.dts).
