Currently for dwc3_usb31 controller, if maximum_speed is limited to super-speed in DT, then device mode is limited to SS, but host mode still works in SSP. The documentation for max-speed property is as follows: "Tells USB controllers we want to work up to a certain speed. Incase this isn't passed via DT, USB controllers should default to their maximum HW capability." It doesn't specify that the property is only for device mode. There are cases where we need to limit the host's maximum speed to SuperSpeed only. Use this property for host mode to contrain host's speed to SuperSpeed.

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.
