The SK-ATM0700D4-Plug is an extension board (provided by the same manufacturer, [1]) which can be connected to the SK-IMX53 panel kit. The panel can be connected either using the RGB parallel bus or using the LVDS connector (recommended). Add DT files describing this "shield", both RGB and LVDS connections.
