[Why] Videos using YUV420 format may result in high power being used. Disabling MPO may result in lower power usage. Update interface that can be used to check power profile of a dc_state.
[How] Allow pstate switching in VBlank as last entry in strategy candidates. Add helper functions that can be used to determine power level: -get power profile after a dc_state has undergone full validation
FWIW this was reverted in the Linus' tree:

drm/amd/display: Revert commit Update Interface to Check UCLK DPM This reverts commit b8d046985c2dc41a0e264a391da4606099f8d44f. Reverting as regression discovered on certain systems and golden values need to updated.Possibly, there are other fixes queued for 6.12, so the revert is not needed anymore?
No, you are right, I need this one. For some reason I thought I had applied it but it failed to apply cleanly and so it was dropped. I'll go fix it up by hand now...
thanks,
