Xe3p_LPD updated fields of registers MBUS_CTL and DBUF_CTL to
accommodate for higher MDCLK:CDCLK ratios. Update the code to use the
new fields.
The field MBUS_TRANSLATION_THROTTLE_MIN_MASK was changed from range
[15:13] to [16:13]. Since bit 16 is not reserved in previous display
IPs and already used for something else, we can't simply extend the mask
definition to include it, but rather define an Xe3p-specific mask and
select the correct one to use based on the IP version.
Similarly, DBUF_MIN_TRACKER_STATE_SERVICE_MASK was changed from range
[18:16] to [20:16]. For the same reasons stated above, it needs a
Xe3p-specific mask definition.
v2:
- Keep definitions in the same line (i.e. without line continuation
breaks) for better readability. (Jani)
v3:
- Keep mask fields sorted by the upper limit. (Matt)
- Extend commit message to indicate why we need Xe3p-specific
definitions of the masks instead of just extending the existing
ones. (Matt)

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.
