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 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)

I'm sorry, but I can't merge this as checkpatch doesn't approve of the
way you write the Co-developed-by, and I don't like it either - in
particular when looking at the 3rd patch,
As this is all from Qualcomm, please change this such that one person
(the author) certifies the origin of the patch (in accordance with DCO
1.1 bullet a). You can attribute the additional authors by writing
"Written in collaboration with Yingying Tang <and other names for the
3rd patch>" above the tags.
PS. Please run checkpatch before sending your patches.
Regards,
Bjorn
