+Subject: [PATCH 0052/2940] drm/amd/display: fix dml handling of mono8/16 pixel
+ formats
+
+mono formats are treated exactly the same as equivallent bpp
+444 formats. Dml validation however lacks 444 8 bit format
+while dml perf param calculation lacks mono format support
+
+This change makes them equivallent as far as the enum is concerned
+to avoid having to update dml
