Can you share an example to add two examples in this binding?
one for usb5e3,608 and other for usb5e3,610, usb5e3,620,
I have tried but I got an error for duplicate

I have tried to modify it with the following example

+allOf:
+  - if:
+      properties:
+        compatible:
+          contains:
+            const: usb5e3,608
+    then:
+      properties:
+        reset-gpios: true
+        vdd-supply: false
+        peer-hub: false
+    else:
+      $ref: usb-device.yaml
+      required:
+        - peer-hub

but it still shows me his warning,

  DTC_CHK Documentation/devicetree/bindings/usb/usb-hcd.example.dtb
/home/amoon/mainline/linux-amlogic-6.y-devel/Documentation/devicetree/bindings/usb/usb-hcd.example.dtb:
hub@1: 'peer-hub' is a required property
        from schema $id: http://devicetree.org/schemas/usb/genesys,gl850g.yaml#

I could not find any binding which supports these properties.
  - reset-gpios
  - vdd-supply
  - peer-hub

Please suggest to me how to resolve this warning.

Thanks
