Discrete onboard USB hubs (an example for such a hub is the Realtek
RTS5411) need to be powered and may require initialization of other
resources (like GPIOs or clocks) to work properly. This adds a device
tree binding for these hubs.

My bot found errors running 'make dt_binding_check' on your patch:

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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

pip3 install dtschema --upgrade

Please check and re-submit.
