[PATCH v1 6/7] ARM: dts: imx6ull-colibri-emmc: Add Toradex Resistive Touch Display 7" Parallel

From: Francesco Dolcini

Date: Thu Oct 01 2026 - 13:56:10 EST


From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx>

Add a device tree overlay for the Resistive Touch Display 7" Parallel
on the Colibri iMX6ULL eMMC parallel RGB LCD interface.

The panel is a LogicTechno LT161010-2NHR 7" WVGA TFT Transmissive LCD
with a resistive touch.

The overlay content is identical to the Colibri iMX7 eMMC one. To
avoid duplicating it, rework the Colibri iMX7 eMMC overlay moving its
content to a new dtsi shared between the two modules, and include it
from both overlays.

The overlay is also combined with the Eval carrier board device tree to
provide a ready-to-use DTB.
