Display driver shall read DPCD 00071h[3:1] during configuration
to get PSR setup time. This register provides the setup time
requirement on the VSC SDP entry packet. If setup time cannot be
met with the current timings
(e.g., PSR setup time + other blanking requirements > blanking time),
driver should enable sending VSC SDP one frame earlier before sending
the capture frame.
BSpec: 69895 (PSR Entry Setup Frames 17:16)
v2: Write frames before su entry to correct register (Ville, Jouni)
Move frames before su entry calculation to it's
own function (Ville, Jouni)
Rename PSR Entry Setup Frames register to indicate
Lunarlake specificity (Jouni)
v3: Modify setup entry frames calculation function to
return the actual frames (Ville)
Match comment with actual implementation (Jouni)
v4: Drop "set" from function naming (Jouni, Ville)
Use i915 instead of dev_priv (Jouni)

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.
