Dear Krzysztof,

Thank you for your reply.

Add dt-bindings for USB2 PHY found on the Nuvoton MA35 SoC.

Please use proper name.

Okay, I will make the correction and use the correct name.

Same here

Okay, I will make the correction and use the correct name.



+
+properties:
+  compatible:
+    enum:
+      - nuvoton,ma35-usb2-phy
All other devices have name ma35d1. Is this a different SoC?

The SoC is the same as ma35d1. I will modify ma35 to ma35d1.

Originally, I intended to create a series of shared drivers.



+
+  "#phy-cells":
+    const: 0
+
+  clocks:
+    maxItems: 1
+    description: USB PHY clock
Drop description, it's obvious.

Okay, I will remove the description.



+
+  clock-names:
+    const: usbd_gate
Drop clock-names, you do not bring any new information.

Okay, I will remove the clock-names.



+
+  nuvoton,sys:
+    $ref: /schemas/types.yaml#/definitions/phandle
+    description:
+      phandle of the system-management node.
Describe what is it for.

Because this driver has some status bits located in the sys, it is necessary to reference the sys link.



+
+required:
+  - compatible
+  - clocks
+  - nuvoton,sys
+  - "#phy-cells"
Keep the same order as in properties.

Okay, I will correct this issue.



+
+additionalProperties: false
+
+examples:
+  - |
+    #include <dt-bindings/interrupt-controller/arm-gic.h>
Where do you use it?

This is not used and will be removed. Thanks for the reminder.



+    #include <dt-bindings/clock/nuvoton,ma35d1-clk.h>
+
+    usb_phy: usb-phy {
+        compatible = "nuvoton,ma35-usb2-phy";
+        clocks = <&clk USBD_GATE>;
+        clock-names = "usbd_gate";
+        nuvoton,sys = <&sys>;
+        #phy-cells = <0>;
+    };

Krzysztof
