f5b2c10b57 drm/amd/display: Don't check registers, if using AUX BL control
[Why]
Currently the driver looks DCN registers to access if BL is on or not.
This check is not valid if we are using AUX based brightness control.
This causes driver to not send out "backlight off" command during power off

18aa989ae1 drm/amd/display: do not skip ODM minimal transition based on new state
[why]
During 8k video plane resizing we could transition from MPC combine mode
back to ODM combine 2:1 + 8k video plane. In this transition minimal
transition state is based on new state with ODM combine enabled.
We are skipping this and it causes corruption because we have to reassign
a current DPP pipe to a different MPC blending tree which is not supported
seamlessly.

3a2c0eccab drm/amd/display: move odm power optimization decision after subvp optimization
[why]
ODM power optimization excludes subvp power optimization but subvp
optimization can override ODM power optimization even if subvp optimization
configuration is not found. This happens with 4k144hz + 1 5k desktop plane.
We could have applied ODM power optimization however this is overridden by
subvp but subvp ends up deciding not apply its optimization.

[how]
Move ODM power optimization decision after subvp so it will try ODM power
optimization after subvp optimization is not possible.

77aac4c280 drm/amd/display: only allow ODM power optimization if surface is within guaranteed viewport size
[why]
Current dc update design has limitation to support transition from
ODM combine to minimum transition to MPC combine state seamlessly
at the capability boundary when MPO plane is resizing. This will
require dc update high level refactor in order to remove the design
limitation. The decision is to block such use case for existing products
by limiting ODM power optimization support for only those surfaces
within guaranteed viewport size. This will prevent us from transitioning
to MPC combine state when ODM power optimization is enabled.

c51d87202d drm/amd/display: do not attempt ODM power optimization if minimal transition doesn't exist
[why]
In some cases such as 8k desktop surface with 144Hz timing, we decide to
enable ODM power optimization but this surface doesn't have a minimum
transition state. Therefore we cannot switch off ODM power optimization seamlessly
This creates path depedency on ODM power optimization decision. i.e
whether or not we should switch off ODM power optimization is dependent
on if the transition to switch off ODM power optimization from current state
is seamless. We don't desire a path dependent power optimization policy
as it is too dynamic and difficult to maintain.

[how]
Attempt ODM power optimization only after we can validate new state without
using pipe combine.

26e5817e39 drm/amd/display: do not block ODM + OPM on one side of the screen
[why]
build scaling param is overriding validation policy regarding small viewport
support. Even if ODM + windowed MPO is not supported. The decision has
to be made at the time of validation. When building scaling params, we might
be building an initial dc state as an input to DML validation. The initial state
is not supposed to be always valid and we rely on DML to modify the initial
dc state and determine the final validation result. This check is pre judging
validation result when building the initial dc state.

This causes an issue where we are transitioning from desktop only ODM
combine 2:1 to ODM bypass with 2 planes. In this case we are building
an initial state with with ODM 2:1 combine + 2 planes. This is indeed not
supported but DML is about to modify the state so it no longer uses ODM
combine. Before it reaches DML, dc resource already fails validation because
it checks that the initial state is not supported by our policy. This overrides
the ODM decision to validate this state with ODM combine disabled. Therefore
causes an unexpected validation failure when the secondary plane is added
on one side of the screen.

This check is not valid if we are using AUX based brightness control.
This causes driver to not send out "backlight off" command during power off
sequence as it already thinks it is off.

[How]
Only check DCN registers if we aren't using AUX based brightness control.

cbb4c9bc55 drm/amd/display: Don't lock phantom pipe on disabling
[Description]
- When disabling a phantom pipe, we first enable the phantom
  OTG so the double buffer update can successfully take place
- However, want to avoid locking the phantom otherwise setting
  DPG_EN=1 for the phantom pipe is blocked (without this we could
  hit underflow due to phantom HUBP being blanked by default)

[Description]
Before enabling the phantom OTG for an update we
must enable DPG to avoid underflow.

47428f4b63 drm/amd/display: limit the v_startup workaround to ASICs older than DCN3.1
Since, calling dcn20_adjust_freesync_v_startup() on DCN3.1+ ASICs
can cause the display to flicker and underflow to occur, we shouldn't
call it for them. So, ensure that the DCN version is less than
DCN_VERSION_3_1 before calling dcn20_adjust_freesync_v_startup().

a81de4a22b Revert "drm/amd/display: Remove v_startup workaround for dcn3+"
This reverts commit 3a31e8b89b.

We still need to call dcn20_adjust_freesync_v_startup() for older DCN3+
ASICs. Otherwise, it can cause DP to HDMI 2.1 PCONs to fail to light up.
