mainlining shenanigans

UCSI already conveys the information about a port's connection status, whether it is operating in UFP or DFP mode, and whether the partner supports USB data or not. This information can be used to notify a dual-role controller to start up its host or peripheral mode accordingly. Add optional support for this by querying each port's fwnode to look for an associated USB role switch device. If present, call usb_role_switch_set() with the determined data role upon Connect Change or Connector Partner Change updates.

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.
