Subject: [PATCH 3/4] arm64: dts: qcom: Add HAMOA-IOT-SOM platform
The HAMOA-IOT-SOM is a compact computing module that integrates a System
on Chip (SoC) — specifically the x1e80100 — along with essential
components optimized for IoT applications. It is designed to be mounted on
carrier boards, enabling the development of complete embedded systems.
This change enables and overlays the following components:
- Regulators on the SOM
- Reserved memory regions
- PCIe6a and its PHY
- PCIe4 and its PHY
- USB0 through USB6 and their PHYs
- ADSP, CDSP
- WLAN, Bluetooth (M.2 interface)
Written with contributions from Yingying Tang (added PCIe4 and its PHY to
enable WLAN).
