[PATCH 4/7] arm64: dts: qcom: Add Arduino Monza (VENTUNOQ) board support

From: Srinivas Kandagatla

Date: Mon Mar 09 2026 - 11:27:27 EST

From: Loic Poulain <loic.poulain@xxxxxxxxxxxxxxxx>

Add device tree support for the Arduino VENTUNOQ board,
based on the Qualcomm QCS8300 (Monaco) SoC.

The board features a Qualcomm Monza SoM and integrates various
peripherals, including:
- USB Type‑C connector with dual‑role support
- ADV7535 DSI‑to‑HDMI bridge
- MAX98091 audio codec
- 2.5G Ethernet PHY (HSGMII)
- PCIe0 (to onboard WiFi chipset and USB bridge)
- PCIe1 (to M2/nvme)
- Button (via GPIO‑keys)
