[PATCH v1 4/4] ARM: dts: ccimx6ulsbcpro: Add support for Goodix touch controller

From: Alex Gonzalez
Date: Thu Oct 25 2018 - 11:10:00 EST


The ConnectCore 6UL SBC Pro has an AUO/Goodix LCD accessory kit that is
connected on the LVDS interface through an on-board LVDS transceiver.

This change adds support for the touch interface.
