a47cc3ab05 drm/amd/display: Raise DPG height during timing synchronization
[Why]
Underflow counter increases in AGM when performing some mode switches due
to timing sync, which is a known hardware issue.

[How]
Temporarily raise DPG height during timing sync so that underflow is not
reported.

7c4ed1df0a drm/amd/display: Copy WM values from set A to other sets in hw_init
[Why]
When we transfer the WM range table to SMU, they can perform a watermark
switch right away. This can be a problem if we're in not in accelerated mode
during hw_init as SMU may initiate a dummy p-state change before the rest
of the watermarks are programmed. Watermark set A is defined to be
sufficient for all cases, so we can copy the values from set A to all other
sets, avoiding any issues from SMU doing WM switches.

[How]
 - new hubbub func init_watermarks
 - copy register values from set A to all other sets
 - call init_watermarks before calling notify_wm_ranges

0a25e8eb95 drm/amd/display: add support for per-state dummy-pstate latency
[why]
Dummy pstate latency actually varies between different
UCLK frequencies, when calculating watermark C, if DAL
always assumes worst case, then it can lead to dummy
pstate not supported scenarios.

[how]
Rather than statically calculating dummy pstate using
worst case, we store the entire table of UCLK to dummy
pstate relationships.  On a per mode basis, we calculate
the actual UCLK lower limit, and use the dynamic worst
case dummy pstate latency.  This prevents the situation
where we don't support full p-state (which will force
high DPM), but still use low DPM dummy pstate latency.

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

[how]

67d09292f8 drm/amd/display: Add SetBacklight call to abm on dmcub
[Why]
Set backlight calls to firmware are are being prevented by dmcu == null
check. Dmcu is expected to be null in this case.

[How]
Only prevent call if dmcu and abm are null.  Also rename variable
'use_smooth_brightness' to 'fw_set_brightness' as it's more appropriate.

868149c9a0 drm/amd/display: Force watermark value propagation
[Why]
The HUBBUB watermark registers are in an area that cannot be power
gated, but the HUBP copies of the watermark values are in areas that can
be power gated. When we power on a pipe, it will not automatically take
the HUBBUB values, we need to force propagation by writing to a
watermark register.

[How]
 - new HUBBUB function to re-write current value in a WM register
 - touch WM register after enabling the plane in program_pipe

c5d5b0ecf9 drm/amd/display: Implement abm config table copy to dmcub
[Why]
Driver must pass abm config table to dmub fw. This provides various
parameters for abm functionality.

[How]
There is too much data to be passed in an inbox message, so we must pass
this data using an indirect buffer.  Copy the table to cw7 via x86,
driver copies to fw_state structure.

eb1b4573c0 drm/amd/display: DPP DTO isn't update properly.
[Why]
before update dpp DTO, we check dppclks in context to determine it is
changed or not, but dppclks in context will be updated anyways after
flip is done, so compare dppclks in context will always get an equal
result.

[How]
Add pipe dpp clks in dccg and compare values between dccg and context.

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.

10b4e64e58 drm/amd/display: program DPG_OFFSET_SEGMENT for odm_pipe
[why]
When test pattern is enabled with ODM combine, test pattern is generated
by piecing multiple DPGs image together.  The current code will program
all DPGs with horizontal offset of 0. This will cause all DPGs to output
the beginning of the pattern. Instead each DPG should program a
horizontal offset of its x position to form a continous pattern when
pieced together.
