[PATCH 02/32] drm/amd/display: Create FPU files for DCN314

Tom Chung chiahsuan.chung at amd.com
Fri Aug 5 17:57:56 UTC 2022


From: Rodrigo Siqueira <Rodrigo.Siqueira at amd.com>

DCN314 has multiple references to FPU operations inside the resource
files, and we need to move those codes to the DML folder. This commit
creates the dcn314_fpu files and moves the bounding box operation to
this file.
