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

Where do you use it?

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

+ usb_phy: usb-phy {
