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Removed outdated dcn references in DML2.1 wrapper.

- For new GFX format passed swizzle_mode to DML.
- For legacy GFX format passed array_mode to DML.
- Dynamically determined the appropriate tiling info based on the

[Description]
This commit ensures that the correct GFX tiling information is passed

63e7ee677c drm/amd/display: Add a left edge pixel if in YCbCr422 or YCbCr420 and odm
[WHY]
On some cards when odm is used, the monitor will have 2 separate pipes
split vertically. When compression is used on the YCbCr colour space on
the second pipe to have correct colours, we need to read a pixel from the
end of first pipe to accurately display colours. Hardware was programmed
properly to account for this extra pixel but it was not calculated
properly in software causing a split screen on some monitors.

[HOW]
The fix adjusts the second pipe's viewport and timings if the pixel
encoding is YCbCr422 or YCbCr420.

An issue was identified in the dcn21_link_encoder_create function where
an out-of-bounds access could occur when the hpd_source index was used
to reference the link_enc_hpd_regs array. This array has a fixed size
and the index was not being checked against the array's bounds before
accessing it.

This fix adds a conditional check to ensure that the hpd_source index is
within the valid range of the link_enc_hpd_regs array. If the index is
out of bounds, the function now returns NULL to prevent undefined
behavior.

[Why]
Current pipe unlock order set within dcn401_interdependent_update_lock.
Separate the logic from the functionality to allow for unit testing
and make it easier to debug.

[How]
Add a flag to indicate if a pipe unlock order should be set.
Create function to determine unlock order.
Indicate which pipes should be unlocked first using
array stored in dc scratch memory.
Pipes indicated in array can be unlocked in any order.

faee3edfcf drm/amd/display: Wait for all pending cleared before full update
[Description]
Before every full update we must wait for all pending updates to be
cleared - this is particularly important for minimal transitions
because if we don't wait for pending cleared, it will be as if
there was no minimal transition at all. In OTG we must read 3 different
status registers for pending cleared, one specifically for OTG updates,
one specifically for OPTC updates, and the last for surface related
updates.

b8dc6ca028 drm/amd/display: Force enable 3DLUT DMA check for dcn401 in DML
[WHY]
Currently TR0 (trip 0) is not properly budgeting for urgent latency in
DML2.1. This results in overly aggressive prefetch schedules that are
vulnerable to request return jitter, resulting in severe underflow at
the start of the frame.

Forcing 3DLUT DMA check to enable causes urgent latency to be budgeted
properly into the prefetch schedule, avoiding the vulnerability.
