fb8cf277b1 drm/amd/display: DP link layer test 4.2.1.1 fix due to specs update
[why]
DP link layer CTS specs updated to change the test parameters in test
4.2.1.1.
Before it requires source to delay 400us on aux no reply.
With the specs updates Errata5, it requires source to delay 3.2ms
(based on LTTPR aux timeout)
This causes our test to fail after updating with the latest test
equipment firmware.

[how]
the change is to allow LTTPR 3.2ms aux timeout delay by default.
And only set to 400us if LTTPR is not present.
Before this piece of logic is interwined with LTTPR support.
Now we will default to 3.2ms aux timeout even if LTTPR support is not
enabled by driver.

63731e73da drm/amd/display: Defer cursor lock until after VUPDATE
[Why]
We dropped the delay after changed the cursor functions locking the
entire pipe to locking just the CURSOR registers to fix page flip
stuttering - this introduced cursor stuttering instead, and an underflow
issue.

The cursor update can be delayed indefinitely if the cursor update
repeatedly happens right around VUPDATE.

The underflow issue can happen if we do a viewport update on a pipe
on the same frame where a cursor update happens around VUPDATE - the
old cursor registers are retained which can be in an invalid position.

This can cause a pipe hang and indefinite underflow.

[How]
The complex, ideal solution to the problem would be a software
triple buffering mechanism from the DM layer to program only one cursor
update per frame just before VUPDATE.

The simple workaround until we have that infrastructure in place is
this change - bring back the delay until VUPDATE before locking, but
with some corrections to the calculations.

This didn't work for all timings before because the calculation for
VUPDATE was wrong - it was using the offset from VSTARTUP instead and
didn't correctly handle the case where VUPDATE could be in the back
porch.

Add a new hardware sequencer function to use the existing helper to
calculate the real VUPDATE start and VUPDATE end - VUPDATE can last
multiple lines after all.

Change the udelay to incorporate the width of VUPDATE as well.

a8665946f3 drm/amd/display: add optc get crc support for timings with ODM/DSC

Optc needs to know if timing is enabled with ODM or DSC before computing
crc.  Otherwise value computed will be inaccurate. Before this change,
the CRC computed without ODM is not equal to the CRC computed with ODM
for the same timing. This is unexpected as we are driving the same
timing despite of the underlaying hardware setup to achieve it. This is
caused by missing hardware programming sequence to support it.

df8e34ac27 drm/amd/display: fix image corruption with ODM 2:1 DSC 2 slice
[why]
When combining two or more pipes in DSC mode, there will always be more
than 1 slice per line.  In this case, as per DSC rules, the sink device
is expecting that the ICH is reset at the end of each slice line (i.e.
ICH_RESET_AT_END_OF_LINE must be configured based on the number of
slices at the output of ODM).  It is recommended that software set
ICH_RESET_AT_END_OF_LINE = 0xF for each DSC in the ODM combine.  However
the current code only set ICH_RESET_AT_END_OF_LINE = 0xF when number of
slice per DSC engine is greater than 1 instead of number of slice per
output after ODM combine.

[how]
Add is_odm in dsc config. Set ICH_RESET_AT_END_OF_LINE = 0xF if either
is_odm or number of slice per DSC engine is greater than 1.

8d8c82b699 drm/amd/display: add worst case dcc meta pitch to fake plane
[why]
When we have single channel memory, we can not light up 2 4k displays
with a 1080p edp, because we don't have enough bw by a small margin.
this small margin comes from dcc meta being too large. We however don't
have this dcc meta when we create fake planes so, before the flip we
will not filter out the mode for 2 4k displays with a 1080p edp

[how]
Change get_default_swizzle_mode to something more general so we don't
end up with a separate function for every missing field in the fake
plane. Add a reasonable dcc meta to the fake plane when it is filled in,
so we filter out modes that don't have enough bandwidth. To do this, we
take the screen width and align it to 1024(8k 60)

be entry points, but instead used as a code reuse/inheritance

Therefore, we want a more clear separation of which functions
we determine to be interface functions vs the functions we
use within hwss.

[Why]
It is confusing to sinks if we send VSC SDP only on some format. Today we
signal colorimetry format using MSA while in formats like sRGB.
But when we switch to BT2020 we set the bit to ignore MSA  colorimetry and
instead use the colorimetry information in the VSC SDP.

But if sink supports signaling of colorimetry via VSC SDP we should always
set the MSA MISC1 bit 6, instead of doing so selectively.

[How]
If sink supports signaling of colorimetry via VSC SDP, and we are sending
the colorimetry info via VSC SDP with packet revision 05h, then always
set MSA MISC1 bit 6.

edb922b022 drm/amd/display: Program DWB watermarks from correct state
[Why]
When diags adds a DWB via a stream update, we calculate MMHUBBUB
paramaters, but dc->current_state has not yet been updated
when the DWB programming happens. This leads to overflow on
high bandwidth tests since the incorrect MMHUBBUB arbitration
parameters are programmed.

[How]
Pass the updated context down to the (enable|update)_writeback functions
so that they can use the correct watermarks when programming MMHUBBUB.

The link trainig always fail.

[How]
1. Modify get_max_link_cap function. According DPALT_DP4

[Why]
When user mode use i2c over aux through ADL or DDI, the function
dal_ddc_service_query_ddc_data will be called. There are two issues.

1. When read/write length > 16byte, current always return false because
the DEFAULT_AUX_MAX_DATA_SIZE != length.
2. When usermode only need to read data through i2c, driver will write
mot = true at the same address and cause i2c sink confused. Therefore
the following read command will get garbage.

[How]
1. Add function dal_dcc_submit_aux_command to handle length > 16 byte.
2. Check read size and write size when query ddc data.
