Linux kernel source tree

Xe2_LPD doesn't have south display engine on a PCH, it's actually on the SoC die (while north display engine is on compute die). As such it makes no sense to go through the PCI devices looking for an ISA bridge. The approach used by BXT/GLK can't be used here since leaving it with PCH_NONE would mean taking the wrong code paths. For the places we currently use a PCH check, it's enough for now to just check the north display version. Use that to define a fake PCH to be used across the driver. Eventually these PCH checks may need to be re-designed as this is already the third platform using/needing a fake PCH. v2: Match on display IP version rather than on platform (Matt Roper) v3: Extend and clarify commit message (Matt Roper / Ville) Signed-off-by: Gustavo Sousa <gustavo.sousa@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230919192128.2045154-6-lucas.demarchi@intel.com |

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.
