Linux kernel source tree

Use the DSC sink device's actual per-slice peak throughput to calculate the minimum number of required DSC slices, falling back to the hard-coded throughput values (as suggested by the DP Standard) if the device's reported throughput value is 0. For now use the minimum of the two throughput values, which is ok, potentially resulting in a higher than required minimum slice count. This doesn't change the current way of using the same minimum throughput value regardless of the RGB/YUV output format used. While at it add a TODO comment for MST tiled displays to calculate the slice count for these based on the total pixel rate of all the tiles. v2: Use drm helpers to query the throughput caps. (Ville) v3: Add TODO comment to account for MST tiled displays.

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.
