You need to add a board-specific compatible here, see:

Documentation/devicetree/bindings/arm/qcom.yaml

> +	chassis-type = "embedded";

The allowed values are:

    enum:
      - desktop
      - laptop
      - convertible
      - server
      - all-in-one
      - tablet
      - handset
      - watch
      - embedded
      - television
      - spectacles

I think it's more of a desktop, but a) that's minor and b) you could
argue either way

Have you cross-checked the regulator settings against the original
vendor-provided sw?

I'm assuming this means the thing can take Qualcomm- (vs OEM-)signed firmware
Could you please confirm that's the case?

The true problem is that this would probably fail validation, so I
suspect this was never tested/checked.

Best regards,

Thanks for the review!
I did test this device-tree with the board.
If you mean some other test, please let me know in detail.

Thanks for the guide!
I tested above command, it was passed for my v1.
Sure, it also passes after I add the board-specific compatible. (not send yet)

> make ... dt_binding_check

Sorry, I never can run this check command. It reports many python syntax error.
I guess the script has issue, or it needs patch to run on my Debian system.
I'll report the issue to upstream separately.

Thanks Konrad for the review!

Thanks for the hint!
I'll add it in v2 series.

The device name indicates it's Mini PC, so desktop is better.

No. Those are from RB3 Gen2. So far there's no issue.
If there's an issue, we can fix it later.

Yes, so far I don't find issue by using gpu firmware from this path.

May I know where it's enabled?
From my search, pon_pwrkey is defined in:
arch/arm64/boot/dts/qcom/pmk8350.dtsi, which is disabled.

The issue may be that once you enable one of these regulators, you'll
