Manasi Navare 0cd7084a2a drm/i915/display/dp: Compute the correct slice count for VDSC on DP
commit f6cbe49be65ed800863ac5ba695555057363f9c2 upstream.

This patch fixes the slice count computation algorithm
for calculating the slice count based on Peak pixel rate
and the max slice width allowed on the DSC engines.
We need to ensure slice count > min slice count req
as per DP spec based on peak pixel rate and that it is
greater than min slice count based on the max slice width
advertised by DPCD. So use max of these two.
In the prev patch we were using min of these 2 causing it
to violate the max slice width limitation causing a blank
screen on 8K@60.

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.
