From: Leonardo Costa <redacted> Add a device tree overlay for the Capacitive Touch Display 7" Parallel on the Apalis iMX6 parallel RGB LCD interface. The panel is a LogicTechno LT161010-2NHC 7" WVGA TFT Transmissive LCD and the touch input is provided by an Atmel MaxTouch capacitive touch controller. The touch controller is connected to the Toradex 10-way Capacitive Touch Interface connector available on Ixora carrier board and Apalis Evaluation Board. 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.
