Could be any class of device, so '@[0-9a-f]+$'

Ideally, we'd convert usb-device.txt to schema and reference it here.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.

You mean we will use different standard node name for each usb class?
e.g.
Use 'ethernet@*' for a usb ethernet adapter, and use 'camera@*' for a
usb camera sensor?

Ok, I'll try to do it.

BTW: Does the compatible support pattern? Is there any example I can
refer to?
