Use intel_ddi_dp_voltage_max() for HSW/BDW too instead of letting these fall through the if ladder in a weird way. This function will look at the actual buf trans tables we have for HSW/BDW to determine the max vswing level. It looks to me like the current code leads HSW port A down the IVB port A path, HSW port B+ and BDW fall through to the very end. Both cases do result in the correct max vswing level 2, but it's very hard to see that from the code.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
