Some USB controllers (such as rk3328 SoC DWC3 controller with INNO USB 3.0 PHY) don't support autosuspend well, when receive remote wakeup signal from autosuspend, the Port Link State training failed, the correct PLC is Resume->Recovery->U0, but when the issue happens, the wrong PLC is Resume->Recovery->Inactive, cause resuming SS port fail. This issue always occurs when connect with external USB 3.0 HUB. This patch adds a quirk to disable xHC USB 3.0 root HUB autosuspend function.

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.
