Mathias Nyman 2be2132007 xhci: Finetune host initiated USB3 rootport link suspend and resume
[ Upstream commit ceca49382ac20e06ce04c21279c7f2868c4ec1d4 ]

Depending on the current link state the steps to resume the link to U0
varies. The normal case when a port is suspended (U3) we set the link
to U0 and wait for a port event when U3exit completed and port moved to
U0.

If the port is in U1/U2, then no event is issued, just set link to U0

If port is in Resume or Recovery state then the device has already
initiated resume, and this host initiated resume is racing against it.
Port event handler for device initiated resume will set link to U0,
just wait for the port to reach U0 before returning.

README

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.
