[Why]
The call currently does two things:
1. Exits DMCUB from idle optimization if it was in
2. Checks DMCUB scratch register to determine if we need to call
DMCUB to do deferred HW restore and then sends the command if it's
ready for it.
By doing (1) we prevent driver idle from being renotified in the cases
where driver had previously allowed DC level idle optimizations via
dc_allow_idle_optimizations since it thinks:
allow == dc->idle_optimizations_allowed
...and that the operation is a no-op.
We want driver idle to be resent at the next opprotunity to do so
for video playback cases.
[How]
Migrate all usecases of dc_z10_restore to only perform (2).
Add extra calls to dc_allow_idle_optimizations to handle (1) and also
keep SW state matching with when we requested enter/exit of DMCUB
idle optimizations.
Ensure cursor idle optimizations false always get called when IPS
is supported.
Further rework/redesign is needed to decide whether we need a separate
level of DM allow vs DC allow and when to attempt re-entry.

[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.

DML2 currently finds assigned pipes in array order rather than the

This change preserves the order of existing pipes and guarantees

[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.

[Why]
SMU uses discrete dpp and disp clock levels. When we submit SMU request
for clock changes in Mhz we need to floor the requested value from Khz so
SMU will choose the next higher clock level in Khz to set. If we ceil to
Mhz, SMU will have to choose the next higher clock level after the ceil,
which could result in unnecessarily jumpping to the next level.
For example, we request 1911,111Khz which is exactly one of the SMU preset
level. If we pass 1912Mhz, SMU will choose 2150,000 khz. If we pass
1911Mhz, SMU will choose 1911,111kHz, which is the expected value.

The vsc infopacket also contains the colorimetry (specifically the

PSR is typically only supported on mobile phone eDP displays, thus this
