In some scenarios it is possible for the encoder assignment module to be

This can lead to incorrect results when querying encoder assignment,
which in turn can cause incorrect displays to be manipulated.

Only allow encoder assignment to be in transient mode of operation when

[why]
1. When HPD deassertion is pulled in the middle of
enabe stream link training, we will abort current training
and turn off PHY. This causes current link settings
to be zeroed this causes later stream enablement
sequence to fail as we prefer to carry on enablement
process despite of link training failure for SST.
2. When HPD is toggled after detection before before
the enable stream sequence as a result. There could be
a race condition where we could end up enable stream based
on the previous link even though the link is updated
after the HPD toggle. This causes an issue where our link
bandwidth is no longer enough to accommodate the timing
therefore causes us to oversubscribe MST payload time
slots. As discussed we decided to add basic sanity check
to make sure that our code can handle the oversubscription
failure silently without system hang.
[how]
1. Keep PHY powered on when HPD is deasserted during
enable stream and wait for the detection sequence to power
it off later.
2. Do not allocate payload if the required timeslot for
current timing is greater than 64 timeslots.

[WHY]
For additional power savings, PSR SU (also referred to as PSR2) can be
enabled on eDP panels with PSR SU support.
PSR2 saves more power compared to PSR1 by allowing more opportunities
for the display hardware to be shut down. In comparison to PSR1, Shut
down can now occur in-between frames, as well as in display regions
where there is no visible update. In otherwords, it allows for some
display hw components to be enabled only for a **selectively updated**
region of the visible display. Hence PSR SU.
[HOW]
To define the SU region, support from the OS is required. OS needs to
inform driver of damaged regions that need to be flushed to the eDP
panel. Today, such support is lacking in most compositors.
Therefore, an in-between solution is to implement PSR SU for MPO and
cursor scenarios. The plane bounds can be used to define the damaged
region to be flushed to panel. This is achieved by:
* Leveraging dm_crtc_state->mpo_requested flag to identify when MPO is
enabled.
* If MPO is enabled, only add updated plane bounds to dirty region.
Determine plane update by either:
* Existence of drm damaged clips attached to the plane (added by a
damage-aware compositor)
* Change in fb id (flip)
* Change in plane bounds (position and dimensions)
* If cursor is enabled, the old_pos and new_pos of cursor plus cursor
size is used as damaged regions(*).
(*) Cursor updates follow a different code path through DC. PSR SU for
cursor is already implemented in DC, and the only thing required to
enable is to set DC_PSR_VERSION_SU_1 on the eDP link. See
dcn10_dmub_update_cursor_data().

- For those DM specific psr config fields, e.g. allow smu opt, is
not to be set/updated from the shared helper but to rely on the

- for the psr version field in psr_config structure, since only

4. DC driver ask DMUB FW to unlock HW lock, but DMUB FW is polling

Protect remove_hpo_dp_link_enc_from_ctx() and release_hpo_dp_link_enc()
with CONFIG_DRM_AMD_DC_DCN as the functions are only called from code
that is protected by CONFIG_DRM_AMD_DC_DCN. Fixes build fail with
-Werror=unused-function.
Fixes: 9b0e0d433f74 ("drm/amd/display: Add dependant changes for DCN32/321")

Revised validation logic when marking for seamless boot. Init resources
accordingly when Pre-OS has ODM enabled. Reset ODM when transitioning
Pre-OS odm to Post-OS non-odm to avoid corruption. Apply logic to set
odm accordingly upon commit.
