Mika Kahola 4b31961a1c drm/i915/display: Calculate crtc clock rate based on PLL parameters
With HDMI monitors we bumped up a case where the crtc clock rate
caused a mismatch on state verification. This was due to
assumption that the SW clock rate from PLL structure would match
the calculated counterpart from HW. This is not necessarily always
the case and therefore we would actually need to recalculate the
clock rate from SW PLL parameters. Then these SW and HW crtc clock
rates can be compared with each other.

The patch recalculates the crtc clock rate for SW state based on
SW PLL parameters and compares the crtc clock rate calculated
from the parameters found from the HW.

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.
