The Realtek RTS5411 is a USB 3.0 hub controller with 4 ports.

This initial version of the binding only describes USB related
aspects of the RTS5411, it does not cover the option of
connecting the controller as an i2c slave.

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.
