The HAMOA-IOT-EVK is an evaluation platform for IoT products, composed of
the Hamoa IoT SoM and a carrier board. Together, they form a complete
embedded system capable of booting to UART.
This change enables and overlays the following peripherals on the carrier
board:
- UART
- On-board regulators
- USB Type-C mux
- Pinctrl
- Embedded USB (EUSB) repeaters
- NVMe
- pmic-glink
- USB DisplayPorts
Written with contributions from Shuai Zhang (added Bluetooth) and Yongxing
Mou (added USB DisplayPorts).

Thanks for pointing that out. I’ll update the node name from
wcn_usb_sw_n_state to wcn-usb-sw-n-state to align with the schema
pattern and eliminate unevaluated property warnings.
Regarding the regulator properties for wcn7850-pmu, as discussed in the
previous version, the required supplies are already configured via UEFI.
Therefore, redefining them in the device tree would be redundant. To
satisfy schema validation without introducing unnecessary definitions, I
plan to use a dummy regulator as a placeholder.
Here’s the pseudocode I intend to use:
dummy_reg: regulator-dummy {
compatible = "regulator-dummy";
};
wcn7850_pmu: wcn7850-pmu@xxxx {
compatible = "qcom,wcn7850-pmu";
reg = <0x...>;
vdd-supply = <&dummy_reg>;
vddaon-supply = <&dummy_reg>;
vdddig-supply = <&dummy_reg>;
vddrfa1p2-supply = <&dummy_reg>;
vddrfa1p8-supply = <&dummy_reg>;
};
This approach ensures the DTB passes schema checks while keeping the
implementation clean and consistent with the actual platform setup. Do
you think this is appropriate?

No. There is no dummy regulator in the hardware, so you cannot add it to
the DTS.

What should I do in this case? Is it acceptable to deviate from the
dt-binding rules due to differences in firmware behavior? Otherwise,
I’ll need to revert to the first version, leave a TODO in the DTS, and
wait for someone to properly model the M.2 card.

The reason we describe the regulators is so that the Wi-Fi can be
powered off and back on. Please don't invent any hacks.
