Matt Roper b8226d62e7 drm/i915/rkl: Handle comp master/slave relationships for PHYs
Certain combo PHYs act as a compensation master to other PHYs and need
to be initialized with a special irefgen bit in the PORT_COMP_DW8
register.  Previously PHY A was the only compensation master (for PHYs
B & C), but RKL adds a fourth PHY which is slaved to PHY C instead.

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.
