8f95ff284c drm/amd/display: add mechanism to skip DCN init
[Why]
If optimized init is done in FW. DCN init be skipped in driver. This
need to be communicated between driver and fw and maintain backwards
compatibility.

[How]
Use DMUB scratch 0 bit 2 to indicate optimized init done in fw and
use DMUB scatch 4 bit 0 to indicate drive supports the optimized flow
so FW will perform it.

c04bd16e48 drm/amd/display: fine tune logic of edid max TMDS clock check
[WHY]
Check max_tmds_clk_mhz firstly will restrict pixel clock under HDMI
1.4, thus HDMI2.0 port can't correctly support 4K 60Hz.

[HOW]
Fine tune the logic to check max_forum_tmds_clk_mhz firstly.

8c44515be1 drm/amd/display: clip plane rects in DM before passing into DC
[Why]
DC global validation can fail when userspace requests to draw large
plane without performing the clipping themselves.

This is observed in the IGT kms_plane panning tests for 4K displays
where they draw an 8K plane without any clipping while expecting only
the top 4K to be drawn.

[How]
DRM already has helpers to take care of the clipping necessary and to
mark whether a plane is visible or not, so make use of these helpers
in DM before passing the plane to DC.

d2e0d8263b drm/amd/display: Fix DML failures caused by doubled stereo viewport
[Why]
Side-by-side and Top-and-bottom stereo configurations fail DML mode
validation due to Viewport exceeded.

This is because we consider the planes as being pipe split in pipe
population so we end up doubling the viewport width, eg. from 4k to 8k.

[How]
These pipes technically aren't hsplit, so add a check for determining
whether is_hsplit should be set.

03ca960098 drm/amd/display: Fix calculation of virtual channel payload
[why]
The calculation of virtual channel payload would not take link settings
in account. As we calculate VCPI slots needed both PBN for stream and
also PBN per time slot.  Before we would use generic PBN per time slot,
which would not change with link settings causing wrong Payload
allocation.

Provide PBN per time slot for each Virtual channel payload calculation.
