[Why]
OLED panels show no display for large vtotal timings.

[How]
Check if ss is enabled and read from lut for spread spectrum percentage.
Adjust dprefclk as required. DP_DTO adjustment is for edp only.

Thomas Zimmermann asked to backmerge -rc6 for drm-misc branches,
there's a few same-area-changed conflicts (xe and amdgpu mostly) that
are getting a bit too annoying.

[Why]
The old asic only have 1 pwrseq hw.
We don't need to map the diginst to pwrseq inst in old asic.

[How]
1. Only mapping dig to pwrseq for new asic.
2. Move mapping function into dcn specific panel control component

[Why]
Without acquiring DMCUB hw lock, a race condition is caused with
Panel Replay feature, which will trigger a hang. Indicate that a
lock is necessary to prevent this when replay feature is enabled.

[How]
To allow dmub hw lock on Replay.

[why]
Audio channel layout for 5.1ch is not correct

[how]
Add the audio layout for 5.1ch (channel_count = 6).
Add divided by zero check.

[Why]
Timings with small HBlank (such as CVT RBv2) can result in insufficient
HBlank bandwidth for audio SDP transmission when DSC is active. This
will cause some higher bandwidth audio modes to fail.

The combination of CVT RBv2 timings + DSC can commonly be encountered
in MST scenarios.

[How]
Add DP audio bandwidth validation for 8b/10b MST and 128b/132b SST/MST
cases and filter out modes that cannot be supported with the current
timing config.

[WHY]
Prepare for enabling the Panel Replay feature

[HOW]
- Add some Panel Replay setting functions in DC
- Add the Panel Replay resource in dcn35_resource.c
- Add debug masks for Panel Replay

[Why]
BL1_PWM_USER_LEVEL is meant for the user brightness level setting from
OS. However, we update it along with other ABM levels to the real PWM
value which could be ABMed.

[How]
Driver to cache and restore the user brightness level setting so that
DMUB can retrieve the last user setting in ABM config initialization.
