From: Vitor Soares <[email protected]> Add a device tree overlay for the Toradex Capacitive Touch Display 7" DSI on the Verdin DSI_1 interface. The display features an internal Texas Instruments SN65DSI83 DSI-to-LVDS bridge driving a Riverdi RVT70HSLNWCA0 7" WSVGA IPS TFT LCD panel. The touch input is provided by an Ilitek ILI2132 capacitive touch controller.
