[Why/How]
LTTPR are required to program DPCD 0000Eh to 0x4 (16ms) upon AUX read
reply to this register. Since old Sinks witih DPCD rev 1.1 and earlier
may not support this register, assume the mandatory value is programmed
by the LTTPR to avoid AUX timeout issues.

[Why]
Urgent latency adjustment was disabled on DCN35 due to issues with P0
enablement on some platforms. Without urgent latency, underflows occur
when doing certain high timing configurations. After testing, we found
that reenabling urgent latency didn't reintroduce p0 support on multiple
platforms.
[How]
renable urgent latency on DCN35 and setting it to 3000 Mhz.

fix was previously in 25.20 but was reverted out as it was accompanied
by other changes that caused regression.
[why&how]
Disabling dtb as the dto src during dpms off relies on in the same
instance being able to also alter the dto src bit to dpref (or not dtb
in general), but this was recently changed to only take place in
dcn31_program_pix_clk, as that is where we want to perform any dto src
changes because tg is off at that point, it is unsafe to do that
elsewhere. What this means is now instead of disabling dtb as dto src
and modifying source bit, we are left with the configuration for a given
tg that specifies dtb as dto src and dtb dto en simultaneously is unset.
dcn31_program_pix_clk can rectify this but its possible for us to
perform some tg dependant operation that would simply hang because when
we go to enable say crtc then, the clk we specify as dto src is "off" en
bit is cleared, source bit was never changed, and program_pix_clk hasnt
been called yet (as apart of dpms on)
We cant disable it as dto src during dpms off if we want the luxury of
performing tg dependant operation during dpms off and before dpms on.

It is possible for an update to acquire otg lock and begin programming
while the previous update has not completed and its values have not
latched. The correct way to go about this is to wait until the vupdate
pulses so we can be sure that previous updates have latched and we can
continue with the current update pipe programming, otherwise during
consecutive full updates we will have corruption flash on the screen.
The corruption flash occurs specifically on configs that require odm
combine, and its local to a specific pipe (will not flash across whole
screen). This ticket is across the otg slave, but it may also appear
across master.

[Why]
HDCP locality check has strict timing requirements, currently broken
due to reliance on msleep which does not guarantee accuracy.
The PR moves the write-poll-read sequence into DMUB using new generic
Fused IO interface, where the timing accuracy is greatly improved.
New flow is enabled using DCN resource capability bit (none for now),
or using a debug flag.
[How]
* Extended mod_hdcp_config with new function for requesting DMUB
to execute a sequence of fused I2C/AUX commands and synchronously
wait until an outbox reply arrives or a timeout expires.
* If the timeout expires, send an abort to DMUB.
* Update HDCP to use the DMUB for locality check if supported.
* Add DC_HDCP_LC_FORCE_FW_ENABLE and DC_HDCP_LC_ENABLE_SW_FALLBACK.
* Make the first enable new flow regardless of resource capabilities.
* Make the second enable fallback to old SW flow.
* Clean up makefile source file listings for easier updates.

[Why]
Due to very small clock register delta between DCN35 and DCN351, clock
spread is being checked on the wrong register for DCN351, causing the
display driver to believe that DPREFCLK downspread to be disabled when
in some stacks it is enabled. This causes the clock values for audio to
be incorrect.
[How]
Both DCN351 and DCN35 use the same clk_mgr, so we modify the DCN35
function that checks for SSC enable to read CLK6 instead of CLK5 when
using DCN351. This allows us to read for DPREFCLK downspread correctly
so the clock can properly compensate when setting values.

[WHY & HOW]
The response of DP BW allocation is handled in Outbox ISR.
When it failed to request the DP BW allocation, it sent another
DPCD request in Outbox ISR immediately. The DP AUX reply also
uses the Outbox ISR. So, no AUX reply happened in this case.
Change to use HPD IRQ for the notification.

[WHY]
We should never apply a minimum dispclk value while in
prepare_bandwidth or while displays are active. This is
always an optimizaiton for when all displays are disabled.
[HOW]
Defer dispclk optimization until safe_to_lower = true
and display_count reaches 0.
Since 0 has a special value in this logic (ie. no dispclk
required) we also need adjust the logic that clamps it for
the actual request to PMFW.

There is a type mismatch between what CalculateDynamicMetadataParameters()
takes and what is passed to it. Currently this function accepts several
args as signed long but it's called with unsigned integers and integer. On
some systems where long is 32 bits and one of these unsigned int params is
greater than INT_MAX it may cause passing input params as negative values.
Fix this by changing these argument types from long to unsigned int and to
int respectively. Also this will align the function's definition with
similar functions in other dcn* drivers.

[Why]
Transitioning from low to high resolutions at high refresh rates caused grey corruption.
During the transition state, there is a period where plane size is based on low resultion
state and ODM slices are based on high resoultion state, causing the entire plane to be
contained in one ODM slice. DML2 would turn off the pipe for the ODM slice with no plane,
causing an underflow since the pixel rate for the higher resolution cannot be supported on
one pipe. This change stops DML2 from turning off pipes that are mapped to an ODM slice
with no plane. This is possible to do without negative consequences because pipes can now
take the minimum viewport and draw with zero recout size, removing the need to have the
pipe turned off.
[How]
In map_pipes_from_plane(), remove "check" that skips ODM slices that are not covered by
the plane. This prevents the pipes for those ODM slices from being freed.
