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
