Mathias Nyman 8a6e963bf2 xhci: Add a flag to disable USB3 lpm on a xhci root port level.
commit 0522b9a1653048440da5f21747f21e498b9220d1 upstream.

One USB3 roothub port may support link power management, while another
root port on the same xHC can't due to different retimers used for
the ports.

This is the case with Intel Alder Lake, and possible future platforms
where retimers used for USB4 ports cause too long exit latecy to
enable native USB3 lpm U1 and U2 states.

Add a flag in the xhci port structure to indicate if the port is
lpm_incapable, and check it while calculating exit latency.

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.
