Ensure that the driver is handling DSC and FEC
enablement properly. FEC can now be independently
enabled without DSC. FEC configuration is also
now performed after link training in order to
avoid link training failures as per the DP spec.
Consequently, DSC can now be left on during
compliance testing. For DSC use-cases, ensure
that the minimum supported bpp is set to 24, as
required by the DSC spec.

During SUI validations and transitions, the encoders
are iterated to find the panel-mode. If concurrent
writeback is enabled, it is assumed as video mode.
Add check to consider only the built-in display
panel mode during sui to avoid wrong interpretation.

DP MST userspace connect and disconnect notifications
are sent from dp_mst_drm. When a MST disconnect event
is notified from dp_mst_drm, the dp_display skips
sending the disconnect event and proceeds to process
the host unready. This is causing graceful dp display
disable to fail and affect the next dp display enable.
DP driver should ideally wait for the graceful disable
of DP display and then proceed. In this change, the DP
driver will wait for the display disable, if enabled,
before proceeding with host_unready.

During transition from sui to non-secure if concurrent
writeback is enabled, it is incorrectly assumed as
video-mode panel. This leads to wrong video-mode
validations and false errors. Fix the check to get the
panel mode only from the primary display.

Display validation will be failed once CRTC and connector

So add this change to get connector roi state even partial
update is disabled.

When LTM hist disable and LTM queue buffer are both queued to driver
in the same commit, if LTM hist disable call is handled by driver first,
all the LTM hist buffers will be moved to buffer_free list. When LTM
queue buffer call is handled, it will try to add the same buffer
to the buffer_free list again, and cause a list double add error.
This change checks if the buffer is already in the buffer_free list
before adding.

This change saves the previous state before moving into the transitional
smmu state, during secure-display/secure-camera usecases. Upon failure
to complete the transition, set smmu state to the previous state.
Previously, smmu state was staying in transitional state.

The DP link layer CTS tests issue continuous DP plug/unplug.
When that happens, sometimes the DP sw state machine is going
into a bad state causing DP blankout. This is happening when
the post_enable call fails and the hpd handling logic in the DP
driver skips sending the disconnect and next subsequent connect
notifications. This change will fix the conditions to correctly
notify the userspace about the DP connection status.

There is an audio turn off timeout error whenever DP handles
the link state toggling requests from sink during audio
playback session. The audio hw is waiting for DMA write done
interrupts before issuing a audio session tear down. As the
DP controller is put into reset before link training, the
DMA write done is not sent by the DP controller hence causing
audio timeout errors. These changes turn off audio before the
DP controller is put into reset so that the audio session
tear down takes place within the stipulated time.

2 Frames transfer pending is possible with posted start.
One ongoing frame and another triggered frame. Current SW
waits for pp_done interrupt if pending frame count is greater
than 1. It is possible that interrupt may be missed for ongoing
frame. In that case, SW should run pp_done wait for one by one
frame instead of two frames together. It allows encoder to
check the ctl scheduler status and trigger the frame done
event on time.

Use one level lower test pattern in case the current
test pattern fails to train link. This helps with few
monitors which sometimes fail with a selected test
pattern. Instead of failing the link, try with a lower
test pattern.
