[PATCH 1/1] arm64: dts: freescale: imx8mm-verdin: Add Toradex DSI to LVDS adapter with the 10.1" V2 display

[Leonardo Costa <leoreis.costa@gmail.com>]

From: Leonardo Costa <leonardo.costa@toradex.com>

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
Verdin 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.
