01130f5260 drm/amd/display: Add hubp cache reset when powergating
[Why]
When HUBP is power gated, the SW state can get out of sync with the
hardware state causing cursor to not be programmed correctly.

[How]
Similar to DPP, add a HUBP reset function which is called wherever
HUBP is initialized or powergated.  This function will clear the cursor
position and attribute cache allowing for proper programming when the
HUBP is brought back up.

b6fcc3867d drm/amd/display: Add support to configure CRC window on specific CRC instance
[Why]
Have the need to specify the CRC window on specific CRC engine.
dc_stream_configure_crc() today calculates CRC on crc engine 0 only and always
resets CRC engine at first.

[How]
Add index parameter to dc_stream_configure_crc() for selecting the desired crc
engine. Additionally, add another parameter to specify whether to skip the
default reset of crc engine.

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Removed outdated dcn references in DML2.1 wrapper.

080950cbdd drm/amd/display: Update dc_tiling_info union to structure
[WHY]
The `dc_tiling_info` union previously did not have a field to
specify the active GFX format, assuming only one format would
be used per DCN version. from DCN4+, support for switching
between different GFX formats is introduced, requiring a way
to track which format is currently in use.

[HOW]
Updated the `dc_tiling_info` union to include a new field that
explicitly indicates the currently used GFX format.
This allows the system to determine the active GFX format
and take the correct programming path accordingly.

[Description]
The union `dc_tiling_info` has been updated to support multiple
GFX formats by adding a new field for identifying the active format.
This update ensures that the correct programming path is followed
based on the selected format. All references to `dc_tiling_info`
in the codebase have been updated to reflect the new structure.

44063dbcdb drm/amd/display: have pretrain for dpia
[WHY]
We like to have pretrain for dpia link so that dp and dp tunneling
have aligned behavior. The Main difficult for dpia pretrain is that
encoder can not get corresponded dpia port when link detection
in current implementation.

[HOW]
1. create enable/disable dpia output functions for dcn35 encoder
and have dpia_id and other necessary info as inputs.
2. dcn35 dpia use the new functions to enable/disable output.
3. have a option to enable/disable the change.

df60dcf5b5 drm/amd/display: Add 3DLUT FL HW bug workaround
[Why]
There is a known HW bug that causes the internal 3DLUT fetch signal to
be lost at VREADY, regardless of whether the OTG lock is being held or
not. A workaround is necessary to make sure that this internal signal
stays up after OTG unlock.

[How]
Set the 3DLUT_ENABLE bit immediately before and after the unlock. Also
use VUPDATE_KEEPOUT to prevent lock transition in the region between
VSTARTUP and VREADY, which could cause issues with this WA sequence.

Also including misc. 3DLUT DMA-related sequence fixes to address a few
regressions causing corruption.

bd870cfd21 drm/amd/display: Add seamless boot support for more DIG operation modes
[Why]
When pre-OS firmware enables display support for displays that operate
the DIG in 2 pixels per cycle processing modes the inferred pixel rate
from get_pixel_clk_frequency_100hz does not account for the true pixel
rate since we're outputting 2 per cycle past the stream encoder.

This causes seamless boot validation to abort early.

[How]
Add a new stream encoder function for getting pixels per cycle from the
stream encoder. If the pixels per cycle is greater than 1 and the driver
policy is to enable 2 pixels per cycle for post-OS then allow seamless
boot to continue.

3c9154310a drm/amd/display: fix dscclk programming sequence on DCN401
[why]
The mux to switch between refclk and dto_dsc_clk is non double buffered.
However dto dsc clk's phase and modulo divider registers are currently
configured as double buffered update. This causes a problem when we switch to
use dto dsc clk and program phase and modulo in the same sequence. In this
sequence dsc clk is switched to dto but the clock divider programming doesn't
take effect until next frame. When we try to program DSCC registers, SMN bus
will hang because dto dsc clk divider phase is set to 0.

[how]
Configure phase and modulo to take effect immediately. Always switch to dto dsc
clk before DSC clock is unagted. Switch back to refclk after DSC clock is gated.

In order to support glitchless display clock ramping for virtual stream,
we must
turn on symclk for stream encoder. The code will power on phy and enable
symclk
for dio encoder during virtual stream dpms sequence.

975507d73c drm/amd/display: Keep VBios pixel rate div setting until next mode set
[why]
Vbios & Driver have difference pixel rate div policy.
When enabling fast boot & performing blank & unblank w/o timing setting,
pixel clock & pixel rate dividor are not match.
It would cause too high pixel reate and eDP would be black screen.

[How]
We would keep pixel rate div setting by Vbios until next timing setting.

f9d48a88eb drm/amd/display: Add left edge pixel for YCbCr422/420 + ODM pipe split
[WHY]
Currently 3-tap chroma subsampling is used for YCbCr422/420. When ODM
pipesplit is used, pixels on the left edge of ODM slices need one extra
pixel from the right edge of the previous slice to calculate the correct
chroma value.

Without this change, the chroma value is slightly different than
expected. This is usually imperceptible visually, but it impacts test
pattern CRCs for compliance test automation.

[HOW]
Update logic to use the register for adding extra left edge pixel for
YCbCr422/420 ODM cases.

[why]
Switching between DSC clock or disable DSC block are not double buffered update.
Corruption is observed if these updates happen before DSC double buffered
disconnection.

[how]
Move DSC disable and refclk reset to post unlock update. Wait for DSC double buffered
disconnection and all mpccs are disconnected before reset DSC clock.
