It is capable of supporting usb3 dual role if there is at least one usb3 port for device and xhci controller, we can check it from the controller's capability, so no need the property "mediatek,usb3-drd" anymore, but I find the property is not decribed in dt-binding. Meanwhile, also take into account if the u3 port is disabled when the u3 phy is shared with pcie.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
