Re: [PATCH 4/4] arm64: dts: qcom: sm6125: Initial support for xiaomi-laurel_sprout

Ok. I think that comment is incorrect. Changing the node name on extcon_usb breaks the "extcon" property in &usb3_dwc3, even after changing the reference.

I'm a bit confused at the "Node name: usb-id" comment. Should I change "extcon_usb" or "extcon-usb" to usb-id?

This commit implements support for the Xiaomi Mi A3
(xiaomi-laurel_sprout). Here's a summary on what's working.

- dmesg output to bootloader preconfigured display
- USB
- UFS
- SMD RPM regulators

Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).

that's missing -pins suffix but most likely it does not match other DTS
neither. So probably was based on some old kernel.

+        pins = "gpio98";
+        bias-disable;
+        drive-strength = <2>;
+    };

Same problems.

+        pins = "gpio98";
+        bias-pull-up;
+        drive-strength = <2>;
+    };
+};
Best regards,
Krzysztof
