Subject: [PATCH] drm/amd/display: Set optimize_pwr_state for DCN31
[Why]
We'll exit optimized power state to do link detection but we won't enter
back into the optimized power state.
This could potentially block s2idle entry depending on the sequencing,
but it also means we're losing some power during the transition period.
[How]
Hook up the handler like DCN21. It was also missed like the
exit_optimized_pwr_state callback.
