[PATCH v1 3/3] ARM: dts: imx7d-colibri-emmc: Add Toradex Resistive Touch Display 7" Parallel

From: Francesco Dolcini

Date: Thu Jul 23 2026 - 06:59:09 EST


From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx>

Add a device tree overlay for the Resistive Touch Display 7" Parallel
on the Colibri iMX7 parallel RGB LCD interface.

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

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