Imre Deak 8ad92b0733 drm/i915/cx0: Read out the Cx0 PHY SSC enabled state
Read out the C10, C20 PHY PLLs SSC enabled state, so the PLL HW/SW state
verification can check this state as well.

C10 PHY PLLs program some PLL registers zeroed out for the non-SSC case,
while programming non-zero values to the same registers for the SSC
case, so check that these PLL registers being zero or non-zero matches
the PLL's overall SSC-enabled state (stored in the
intel_c10pll_state::ssc_enabled flag).

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.
