[PATCH v2 4/7] arm64: dts: freescale: imx8mm-verdin: Add Toradex Capacitive Touch Display 10.1" DSI

From: Ernest Van Hoecke

Date: Fri Jul 24 2026 - 12:48:20 EST

From: Ernest Van Hoecke <ernest.vanhoecke@xxxxxxxxxxx>

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 IPS TFT LCD panel. The touch input is
provided by an Ilitek ILI2132 capacitive touch controller.

The overlay is also combined with the Verdin iMX8M Mini Dahlia carrier
board device trees to provide ready-to-use DTBs in both WiFi and
non-WiFi SoM variants.
