Some special SoCs (e.g. rk322xh) USB3 PHY have problem to detect disconnection, they lose the ability to detect an absence of Rx termination specified in USB3 spec Table 6-21, fortunately, the USB3 PHY can detect port link state change when USB3 device is unplugged, so we can do soft disconnect according to the PLC.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
