Jingwen Zhu e0cce12251 drm/amd/display: Improvement for handling edp link training fails
[Why]
The eDP retrain will cause the DPCD 300 to be reset to default.
And cause the brightness can't be set correctly.

[How]
delete the call to edp panel power control in both
enable_link_output/disable_link_output entirely and
only call edp panel control in enable_link_dp and 
disable_link_dp once.

Michael Mityushkin 56d8ce9d8c drm/amd/display: Apply correct panel mode when reinitializing hardware
[Why]
When link training during engine recovery, ASSR might fail causing panel
mode to be reset to default. This should not happen for eDP as it
will prevent the panel from turning back on.

[How]
Added dp_panel_mode to struct dc_link to remember previously applied
panel mode. Do not reset panel mode to default while performing link
training if previously used panel mode = eDP.

Wesley Chalmers ce560ac402 drm/amd/display: Block optimize on consecutive FAMS enables
[WHY]
It is possible to commit state multiple times in rapid succession with
FAMS enabled; if each of these commits were to set optimized_required,
then the user may see latency.

[HOW]
fw_based_mclk_switching is currently not used in dc->clk_mgr; use it
to track whether the current state has FAMS enabled;
if it has, then do not disable FAMS in prepare_bandwidth, and do not set
optimized_required.

Wesley Chalmers 474f01015f drm/amd/display: Do not set drr on pipe commit
[WHY]
Writing to DRR registers such as OTG_V_TOTAL_MIN on the same frame as a
pipe commit can cause underflow.

[HOW]
Move DMUB p-state delegate into optimze_bandwidth; enabling FAMS sets
optimized_required.

This change expects that Freesync requests are blocked when
optimized_required is true.

Hamza Mahfooz 6f6869dcf4 drm/amd/display: prep work for root clock optimization enablement for DCN314
To enable root clock optimizations, we need a number of
register writes and need to account for the difference
in DPSTREAMCLK between DCN31 and DCN314. To prevent
issues, add a number of register writes to
DCCG_MASK_SH_LIST_DCN314_COMMON(), and define dccg314_init()
which is mostly in alignment with dccg31_init() but
accounts for the new DPSTREAMCLK sequence.

[Why]
Some dock and mst monitor don't like to receive CLEAR_PAYLOAD_ID_TABLE
when mst_en is set to 0. It doesn't make sense to do so in source
side, either.

[How]
Don't send CLEAR_PAYLOAD_ID_TABLE if mst_en is 0
