Marcin Bachry 846ba58a7c PCI: Increase D3 delay for AMD Renoir/Cezanne XHCI
[ Upstream commit e0bff43220 ]

The Renoir XHCI controller apparently doesn't resume reliably with the
standard D3hot-to-D0 delay.  Increase it to 20ms.

[Alex: I talked to the AMD USB hardware team and the AMD Windows team and
they are not aware of any HW errata or specific issues.  The HW works fine
in Windows.  I was told Windows uses a rather generous default delay of
100ms for PCI state transitions.]

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.
