c6888879fd drm/amd/display: Fix 6x4K displays light-up on Vega20 (v2)
[Why]
More than 4x4K didn't lightup on Vega20 due to low dcfclk value.
Powerplay expects valid min requirement for dcfclk from DC.

[How]
Update min_dcfclock_khz based on min_engine_clock value.

v2: backport to 4.20 (Alex)

1a0e348e56 drm/amd/display: Disable 4k 60 HDMI on DCE11
[Why]
Carrizo and Stoney have severe corruption when trying to power
4k 60 monitors over HDMI connectors that support 4k 60.

Carrizo and Stoney require retimers and redrivers to support 4k 60
over HDMI.  This driver does not currently support these.  Thus, 4k 60
HDMI (and all other modes requiring over 300MHz) should be disabled.

[How]
Reduce the dce11 HDMI pixel clock cap to 300000kHz.

6c0984d53b drm/amd/display: Raise dispclk value for dce_update_clocks
[Why]

The DISPCLK value was previously requested to be 15% higher for all
ASICS that went through the dce110 bandwidth code path. As part of a
refactoring of dce_clocks and dce110 set_bandwidth this was removed
for power saving considerations.

This changed caused corruption under certain display configurations.
Originally thought to be Vega specific, it was also observed on Polaris.

[How]

The 15% is brought back but its placement differs from the original
patch. This boost should only be enable while DFS bypass is inactive.

This (like the Vega patch) is also a workaround that should be
removed after the root cause is identified.

599760d6d0 drm/amd/display: Fix Vega10 lightup on S3 resume
[Why]
There have been a few reports of Vega10 display remaining blank
after S3 resume. The regression is caused by workaround for mode
change on Vega10 - skip set_bandwidth if stream count is 0.
As a result we skipped dispclk reset on suspend, thus on resume
we may skip the clock update assuming it hasn't been changed.
On some systems it causes display blank or 'out of range'.

fb2b1ea325 drm/amd/display: program v_update and v_ready with proper field
[WHY]
There are two different variables used to calculate v_update and v_ready,
one for validation and the other for performance parameter calculation.
Before the variable for validation was used which caused underflow on
1080edp with vsr enabled

[HOW]
program v_update and v_ready with the variables for performance parameter
calculation

b07971d43c drm/amd/display: stop using switch for different CS revisions
Clock sources currently have support for asic specific
function pointers. But actual separation into functions
was never performed, leaving us with giant functions that
rely on switch.

This change creates separate functions, removing switch use.

cae50a43b9 drm/amd/display: use link type to decide stream enc acquisition
[Why]
Virtual sink is used when set mode happens on a disconnected display
to allow the mode set to proceed. This did not work with MST because
the logic for acquiring stream encoder uses stream signal to determine
the special handling is required, and stream signal is virtual instead
of DP in this case.

[How]
Use link type to decide instead.

2 I2C/AUX engines are created. Within dc_link_aux_transfer, when
pin_data_en =2, refer to enengines[ddc_pin->pin_data->en] = NULL.
NULL point is referred later causing system crash.
