[ Upstream commit11bf53a38c] The PCIe QMP PHY requires different programming sequences when being used for the RC (Root Complex) or for the EP (End Point) modes. Allow selecting the submode and thus selecting a set of PHY programming tables. Since the RC and EP modes share common some common init sequence, the common sequence is kept in the main table and the sequence differences are pushed to the extra tables.

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.
