The Designware controller has common registers to set number of fast training sequence ordered sets. The Artpec6, Intel, and Tegra driver initialize these register fields. Let's move the initialization to the common setup code and drivers just have to provide the value. There's a slight change in that the common clock mode N_FTS field is now initialized. Previously only the Intel driver set this. It's not clear from the code if common clock mode is used in the Artpec6 or Tegra driver. It depends on the DWC configuration. Given the field is not initialized while the others are, it seems unlikely common clock mode is used.

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.
