[PATCH 2/2] arm64: dts: qcom: Add base HAMOA-IOT-COME board

From: Yuanjie Yang

Date: Tue Jun 30 2026 - 03:12:58 EST


Add the device tree for the HAMOA-IOT-COME platform.

The system consists of a SoM mounted on a carrier board. The HAMOA-IOT-COME
SoM integrates the core system, including a SiP that contains the SoC and
related components.

Hierarchy:

Carrier Board
-> SoM
-> SiP
-> SoC

The SiP on the HAMOA-IOT-COME SOM is equivalent to the HAMOA-IOT-EVK SoM.

The initial device tree includes support for:
- UART
- Regulators
- USB
- PCIe
- Pinctrl
- ADSP, CDSP
- UFS
- Graphic
- Video
