From: Vitor Soares <vitor.soares at toradex.com>
Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
DSI on the Aquila DSI_1 interface. Used on the Clover Board (J12), where
DSI_1 is exposed via a FFC/FPC connector.
The display includes an internal Texas Instruments SN65DSI83 DSI-to-LVDS
bridge driving a Riverdi RVT101HVLNWC00 10.1" WXGA IPS TFT LCD panel.
Touch input is provided by an Ilitek ILI2132 capacitive touch controller.
The overlay is also combined with the Aquila AM69 Clover carrier board
device tree to provide a ready-to-use DTB.
