Matt Roper 5767dc9e2d drm/i915/gen12: Update combo PHY init sequence
The bspec was updated with a minor change to the 'DCC mode select'
setting to be programmed during combo PHY initialization.

v2:
 - Keep the opencoded rmw behavior instead of switching to
   intel_de_rmw().  We need to read from a _LN register, but write to
   the _GRP register to update all lanes.

Bspec: 49291

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.
