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 Iris v2 and Aster carrier boards. The overlay is also combined with the Iris v2 and Aster carrier board device tree to provide a ready-to-use DTB.
