Mario Limonciello 0a0097e2b9 drm/amd/display: Avoid configuring PSR granularity if PSR-SU not supported 
[ Upstream commit a5ce8695d6 ]

[Why]
If PSR-SU is disabled on the link, then configuring su_y granularity in
mod_power_calc_psr_configs() can lead to assertions in
psr_su_set_dsc_slice_height().

[How]
Check the PSR version in amdgpu_dm_link_setup_psr() to determine whether
or not to configure granularity.

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.
