63ab80d9ac drm/amd/display: DML2.1 Post-Si Cleanup
[Why]
There are a few cleanup and refactoring tasks that need to be done
with the DML2.1 wrapper and DC interface to remove dependencies on
legacy structures and N-1 prototypes.

[How]
Implemented pipe_ctx->global_sync.
Implemented new functions to use pipe_ctx->hubp_regs and
pipe_ctx->global_sync:
- hubp_setup2
- hubp_setup_interdependent2
- Several other new functions for DCN 4.01 to support newer structures

Removed dml21_update_pipe_ctx_dchub_regs
Removed dml21_extract_legacy_watermark_set
Removed dml21_populate_pipe_ctx_dlg_param
Removed outdated dcn references in DML2.1 wrapper.

a29997b7ac drm/amd/display: Limit VTotal range to max hw cap minus fp
[WHY & HOW]
Hardware does not support the VTotal to be between fp2 lines of the
maximum possible VTotal, so add a capability flag to track it and apply
where necessary.

5fd95dab60 drm/amd/display: Remove last parts of timing_trace
Commit c2c2ce1e96 ("drm/amd/display: Optimize passive update planes.")
removed the last caller of context_timing_trace.
Remove it.

With that gone, no one is now looking at the 'timing_trace' flag, remove
it and all the places that set it.

1791bd09af drm/amd/display: Add hpd_source index out-of-bounds check for dcn3x link encoder creation
This patch adds a boundary check for the hpd_source index during the
link encoder creation process for dcn3x IP's. The check ensures that the
index is within the valid range of the link_enc_hpd_regs array to
prevent out-of-bounds access.

3c6ad7320b drm/amd/display: Remove unreachable check
[WHY]
Coverity analysis flagged this code as DEADCODE
since the condition and return in the outer loop
are never reached.

All operations with the 'dwb_pipe' variable happen
in the inner loop, that already contains the same
check with the 'MAX_DWB_PIPES'. The later
check condition cannot occur before the check
condition in the inner loop, thus the later
condition is unreacable.

[HOW]
Remove the unreachable condition.

e69d43356f drm/amd/display: Move fpo_in_use to stream_status
[Description]
Refactor code and move fpo_in_use into stream_status to avoid
unexpected changes to previous dc_state (i.e., current_state).
Since stream pointers are shared between current and new dc_states,
updating parameters of one stream will update the other as well
which causes unexpected behaviors (i.e., checking that fpo_in_use
isn't set in previous state and set in the new state is invalid).
To avoid incorrect updates to current_state, move the fpo_in_use flag
into dc_stream_status since stream_status is owned by dc and are not
shared between different dc_states.

ae308e93db drm/amd/display: Restrict multi-disp support for in-game FAMS
[HOW&WHY]
In multi-monitor cases the VBLANK stretch that is required to align both
monitors may be so large that it may create issues for gaming performance.

Use debug value to restrict in-game FAMS support for multi-disp use case.

aece2094e3 drm/amd/display: Fix compiler warnings on high compiler warning levels
[why]
Enabling higher compiler warning levels results in many issues that can
be trivially resolved as well as some potentially critical issues.

[how]
Fix all compiler warnings found with various compilers and higher
warning levels.  Primarily, potentially uninitialized variables and
unreachable code.

f0ec30549a drm/amd/display: Ensure populate uclk in bb construction
[Description]
- For some SKUs, the optimal DCFCLK for each UCLK is less than the
  smallest DCFCLK STA target due to low memory bandwidth. There is
  an assumption that the DCFCLK STA targets will always be less
  than one of the optimal DCFCLK values, but this is not true for
  SKUs that have low memory bandwidth. In this case we need to
  populate the optimal UCLK for each DCFCLK STA targets as the max
  UCLK freq.
- Also fix a bug in DML where start_state is not assigned and used
  correctly.
