Ville Syrjälä 6481d5ed07 drm/i915: Disable GMBUS clock gating around GMBUS transfers on gen9+
Gen9+ need to disable GMBUS clock gating when doing multi part
transfers. Otherwise clock gating will kick in when GMBUS is in
the WAIT state and presumably that will corrupt the transfer.
This is documented as Display WA #0868.

Apparently older hardware doesn't allow clock gating in the WAIT
state and thus are unaffected by this problem.

v2: Limit the PCH w/a to gen9 and gen10 only (DK)
    Actually change it to check the PCH type instead since
    it's the PCH that actually contains the GMBUS hardware

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
