[PATCH v1 06/15] arm64: dts: ti: k3-am62-verdin: Add Toradex Capacitive Touch Display 10.1" DSI

[Vitor Soares <ivitro@gmail.com>]

From: Vitor Soares <vitor.soares@toradex.com>

Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
on the Verdin DSI_1 interface. The display features an internal
Texas Instruments SN65DSI83 DSI-to-LVDS bridge driving a Riverdi
RVT101HVLNWC00 10.1" WXGA (1280x800) IPS TFT LCD panel. The touch input
is provided by an Ilitek ILI2132 capacitive touch controller.

The overlay is also combined with the Verdin AM62 Dahlia carrier board
device trees to provide ready-to-use DTBs in both WiFi and non-Wifi SoM
variants.
