Stanislav Lisovskiy beb2998002 drm/i915: Corrupt DSI picture fix for GeminiLake
Currently due to regression CI machine displays show corrupt picture.
Problem is when CDCLK is as low as 79200, picture gets unstable, while
DSI and DE pll values were confirmed to be correct.  Limiting to 158400
as agreed with Ville.

We could not come up with any better solution yet, as PLL divider values
both for MIPI(DSI PLL) and CDCLK(DE PLL) are correct, however seems that
due to some boundary conditions, when clocking is too low we get wrong
timings for DSI display.  Similar workaround exists for VLV though, so
just took similar condition into use. At least that way GLK platform
will start to be usable again, with current drm-tip.

v2: Fixed commit subject as suggested.

v3: Added generic bugs(crc failures, screen not init
for GLK DSI which might be affected).

v4: Added references tag for bugs affected.

README

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.
