[PATCH 06/13] drm/amd/display: move FPU associated DCN302 code to DML folder
Wayne Lin
Wayne.Lin at amd.com
Fri Jan 14 01:36:50 UTC 2022
From: "Dhillon, Jasdeep" <Jasdeep.Dhillon at amd.com>
[Why & How]
As part of the FPU isolation work documented in
https://patchwork.freedesktop.org/series/93042/, isolate
code that uses FPU in DCN302 to DML, where all FPU code
should locate.
