cbfac7fa49 drm/amd/display: fix memory leak when using debugfs_lookup()
When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time.  Fix this up by properly
calling dput().

7b471c32e4 drm/amd/display: Fix black flash when switching from ODM2to1 to ODMBypass
[Why]
On secondary display hotplug we switch primary
stream from ODM2to1 to ODMBypass mode. Current
logic will trigger disabling front end for this
stream.

[How]
We need to check if prev_odm_pipe is equal to NULL
in order to disable dangling planes in this scenario.

f5b9c1ffab drm/amd/display: Re-initialize viewport after pipe merge
[Why]
Pipes get merged in preparation for SubVP but if they don't get used, and
are in ODM or some other multi pipe config, it would calculate the
voltage level with a viewport of just one pipe from when they were split
resulting in too low of a voltage level.

[How]
Made it so that the viewport and other timing settings get rebuilt and re-
initialized after the pipe merge, before calculating the voltage level so it
would calculate it correctly.

94a82c9e3d drm/amd/display: disable display fresh from MALL on an edge case for DCN321
[Why&How]
When using a 4k monitor when cursor caching is not supported due to
framebuffer being on an uncacheable address, enabling display refresh
from MALL would trigger corruption if SS is enabled.

Prevent entering SS if we are on the edge case and cursor caching is not
possible. Do this only if cursor size larger than a 64x64@4bpp. Pull the
cursor size calculation out of if condition since cursor address may not
be set on all platforms

507fd7c400 drm/amd/display: Fix DCN32 DPSTREAMCLK_CNTL programming
[Why]
Each index in the DPSTREAMCLK_CNTL register
phyiscally maps 1-to-1 with HPO stream encoder
instance. On the other hand, each index in
DTBCLK_P_CNTL physically maps 1-to-1 with OTG
instance.

Current DCN32 DPSTREAMCLK_CLK programing assumes
that OTG instance always maps 1-to-1 with
HPO stream encoder instance. This is not always
guaranteed and can result in blackscreen.

[How]
Program the correct dpstreamclk instance with
the correct dtbclk_p source.

19f7b83344 drm/amd/display: Update clock table policy for DCN314
[Why & How]
Depending on how the clock table is constructed from PMFW we can run
into issues where we don't think we have enough bandwidth available
due to FCLK too low - eg. when the FCLK table contains invalid entries
or a single entry.

We should always pick up the maximum clocks for each state as a final
state in this case to prevent validation from failing if the table is
malformed.

We should also contain sensible defaults in the case where values
are invalid.

Redfine the clock table structures by adding a 314 prefix to make
debugging these issues easier by avoiding symbol name clashes.

Overall this policy more closely aligns to how we did things for 315,
but because of how the voltage rail is setup we should favor keeping
DCFCLK low rather than DISPCLK or DPPCLK - so use the max for those
in every entry.

dd49c07f3a drm/amd/display: Modify header inclusion pattern

Recent backport from opensource broke the Nightly tool build
that tests DC and DML for bugs and regressions. This was
because the backport had a header inclusion that was not
consistent with the AMD style of including headers was allowed
to be merged back in DML code that caused tool compilation
failures.

[How]
Modify the way in which the header file in included so that it
is consistent with AMD style of including headers. This then
automatically fixes the tool compilation process and also
helps maintain the code quality and consistency.

04fb918bf4 drm/amd/display: Fix pixel clock programming
[Why]
Some pixel clock values could cause HDMI TMDS SSCPs to be misaligned
between different HDMI lanes when using YCbCr420 10-bit pixel format.

BIOS functions for transmitter/encoder control take pixel clock in kHz
increments, whereas the function for setting the pixel clock is in 100Hz
increments. Setting pixel clock to a value that is not on a kHz boundary
will cause the issue.

[How]
Round pixel clock down to nearest kHz in 10/12-bpc cases.

acc96ae0d1 drm/amd/display: set panel orientation before drm_dev_register
To set the panel orientation property with quirk, we need the mode size
provided by EDID. This info is available after EDID is read by dc_link_detect()
and updated by amdgpu_dm_update_connector_after_detect(). The detection
happens at driver load in amdgpu_dm_initialize_drm_device() and,
therefore, we can get modes and set panel orientation before
drm_dev_register() to avoid DRM warns on creating the connector property
after device registration:

30456ffa65 drm/amd/display: Fix TDR eDP and USB4 display light up issue
[Why]
After TDR recovery, eDP and USB4 display does not light up. Because
dmub outbox notifications are not enabled after dmub reload and link
encoder assignments for the streams are not cleared before dc state
reset.

[How]
- Dmub outbox notification is enabled after tdr recovery by issuing
  inbox command to dmub.
- Link encoders for the streams are unassigned before dc state reset.
