combinations.

If DP_EARLY_8B10B_TPS2 chip cap is set, this new sequence programs phy

LTTPR training pattern register as instructed by vendor.

sampling_rate is an uint8_t but is assigned an unsigned int, and thus it
can overflow. As a result, sampling_rate is changed to uint32_t.
Similarly, LINK_QUAL_PATTERN_SET has a size of 2 bits, and it should
only be assigned to a value less or equal than 4.

[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.

For multi-GPU systems it is difficult to tell which GPU a particular
message is being printed for and that is undesirable because it
complicates debugging efforts. Also, the new macros allow us to enable
logging for particular parts of the codebase more selectively (since we
no longer need to throw everything at DRM_DEBUG_KMS()). So, for the
reasons outlined above we should switch to the new macros.
We can accomplish this by using the existing DC_LOGGER code to pass
around the relevant `struct drm_device` which will be fed to the new
macros in logger_types.h. Also, we must get rid of all instances of the
DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use
the DC logger there and we can simply refer to the macros directly
there instead.

In some instances, the GPU is transmitting repeated frame to the sink
without any updates or changes in the content. These repeat transmission
are wasteful, resulting in power draw in different aspects of the system
1. DCN is fetching the frame of data from DF/UMC/DRAM. This memory traffic
prevents power down of parts of this HW path.
2. GPU is transmitting pixel data to the display through the main link of
the DisplayPort interface. This prevents power down of both the Source
transmitter (TX) and the Sink receiver (RX)
The concepts of utilizing replay is similar to PSR, but there is a benefit of:
Source and Sink remaining synchronized which allows for
- lower latency when switching from replay to live frames
- enable the possibility of more use cases
- easy control of the sink's refresh rate during replay
Due to Source and Sink remaining timing synchronized, Replay can be activated
in more UI scenarios.
