From: Leonardo Costa <[email protected]> Add a device tree overlay for the Toradex DSI to LVDS Adapter with the Toradex Capacitive Touch Display 10.1" LVDS V2. The adapter connects to the Aquila DSI_1 interface. It is based on the Texas Instruments SN65DSI84 DSI-to-LVDS bridge and drives an Opto Logic SCX1001511GGC49 10.1" WXGA TFT LCD LVDS panel. Touch input is provided by an ILITEK ILI251x capacitive touch controller.
