In TBT-alt mode the driver doesn't program the PHY's PLL, which is
handled instead by Thunderbolt driver/FW components, hence the PLL's HW
vs. SW state verification should be skipped. During HW readout set a flag
in the PLL state if the port was at the moment in TBT-alt mode and skip
the verification of PLL parameters in this case.

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 reStructuredText 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.
