Atm TGL supports only a fixed set of valid DSC compressed bpps (6,8,10,12,15), but this is not taken into account while looking for a bpp in the minimum..maximum compressed bpp range. This happened to work only by chance since atm from the above min..max range it's always the maximum bpp that is selected, which is one of the above valid bpps (see mst_stream_dsc_compute_link_config() -> intel_dp_dsc_nearest_valid_bpp()). Before selecting a bpp however, the bpp's BW requirement should be checked wrt. to the MST total link BW; after doing that - in a follow-up change - the validity of any bpp in the min..max range must be ensured before the bpp is selected, do that here.

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.
