2b1245f3ec drm/i915/mst: pass intel_dp around in mst stream helpers 
All of the functions in question operate on the primary encoder, and
more specifically the primary intel_dp, so pass it around instead of the
encoder for less ambiguity.

f635e7657e drm/i915/display/xe3lpd: Avoid setting YUV420_MODE in PIPE_MISC 
For Xe3_LPD the PIPE_MISC YUV420 Enable (bit 27), already implies enabling
full blend YUV420 mode and YUV420 Mode (bit 26) is removed.
Therefore, avoid setting YUV420 Mode for Xe3_LPD+ while programming
PIPE_MISC for YCbCr420 output format.

d58f65df2d drm/i915/dp_mst: Fix connector initialization in intel_dp_add_mst_connector() 
The connector initialization in intel_dp_add_mst_connector() depends on
the device pointer in connector to be valid, at least by connector
debug printing. The device pointer is initialized by drm_connector_init(),
however that function also exposes the connector to in-kernel users,
which can't be done before the connector is fully initialized. For now
make sure the device pointer is valid before it's used, until a
follow-up change moving this to DRM core.

This issue was revealed by the commit in the Fixes: line below, before
which the above debug printing checked and handled a NULL device pointer
gracefully in DRM core.

90b63bd4a6 drm/i915/dp: Limit max compressed bpp to 18 when forcing DSC 
While forcing DSC when it is not actually required, the max compressed
bpp from the source gets picked for compression for some pipe bpps.
Apparently, when DSC is not required, forcing DSC to the maximum compressed
bpp seems to cause underruns.

To avoid this, limit the max compressed bpp to 18 while forcing DSC. This
value works across platforms with different pipe bpps and prevents
underruns.

4449955949 drm/i915/hdcp: Fix when the first read and write are retried 
Make sure that the first read/write in hdcp2_authentication_key_exchange
are only retried when we have either DP/DPMST encoder connected,
since we do this to give docks and dp encoders some extra time to
get their HDCP DPCD registers ready only for DP/DPMST encoders as
this issue is only observed here no need to burden other encoders
with extra retries as this causes the HDMI connector to have some
other timing issue and fails HDCP authentication.

--v2
-Add intent of patch [Chaitanya]
-Add reasoning for loop [Jani]
-Make sure we forfiet the 50ms wait for non DP/DPMST encoders.

--v3
-Remove the is_dp_encoder check [Jani/Chaitanya]
-Make the commit message more clearer [Jani]

in all phases of the atomic commit, whereas the other apporoach only
really works during .atomic_check().
