last piece of work to enable this was commit c92b7fe0d92a
("drm/amd/display: move remaining FPU code to dml folder")
and this has since been backported to 6.1 stable (in 6.1.7).

This adds ARM64 support into the DCN. This mainly enables support
for Navi graphics cards. The dcn10 changes haven't been tested,
since I don't have the relevant hardware available, but there
is no way to conditionally disable them, so I've done them anyway.

This is likely the real fix for issues such as
https://gitlab.freedesktop.org/drm/amd/-/issues/1215, or perhaps
https://gitlab.freedesktop.org/drm/amd/-/issues/1191, and should
be probably backported into existing stable trees.

The dcn20_validate_bandwidth function would have code touching the
incorrect registers emitted outside of the boundaries of the
DC_FP_START/END macros, at least on ppc64le. Work around the
problem by wrapping the whole function instead.

The proper solution is already being discussed, it seems:
