+Subject: [PATCH 3080/4256] drm/amd/display: populate last calculated bb state
+ with max clocks
+
+[why]
+update_bounding_box calculates intermediate bb states based on clock relationship
+however, the last state doesn't need to maintain a minimum relationship, but should
+actually contain maximum of every clock.  otherwise maximum clocks are not usable
+
+[how]
+once the calculated bb is built, override the last state with max values
