[why]
Need a helper function to check idle power is allowed
so that dc doesn't access any registers that are power-gated.
[how]
Implement helper function to check idle power optimization.
Enable a hook to check if detection is allowed.

[why]
Clip size increase will increase viewport, which could cause us to
switch to MPC combine.
If we skip full update, we are not able to change to MPC combine in
fast update. This will cause corruption showing on the video plane.
[how]
treat clip size increase of a surface larger than 5k as a full update.

[WHAT]
hw_points_num is 0 before ogam LUT is programmed; however, function
"dwb3_program_ogam_pwl" assumes hw_points_num is always greater than 0,
i.e. substracting it by 1 as an array index.
[HOW]
Check hw_points_num is not equal to 0 before using it.

DC code is reused by other OSes and so Linux return codes don't
make sense. Change dc_set_power_state() to boolean and add a wrapper
dm_set_power_state() to return a Linux error code for the memory

dc->caps.color.mpc.gamut_remap says there is a post-blending color block
for gamut remap matrix for DCN3 HW family and newer versions. However,
those drivers still follow DCN10 programming that remap stream
gamut_remap_matrix to DPP (pre-blending).
To enable pre-blending and post-blending gamut_remap matrix supports at
the same time, set stream gamut_remap to MPC and plane gamut_remap to
DPP for DCN families that support both.
It was tested using IGT KMS color tests for DRM CRTC CTM property and it
preserves test results.

[why]
The current ODM change detection only compares first two ODM slices.
If there are 4 ODM slices and the change is within the last two slices, the
logic fails to detect ODM change and cause us to skip ODM programming
unexpectedly.
[how]
Add a is ODM topology changed resource interface to check any ODM
topology changes with a more generic method.

For multi-GPU systems it is difficult to tell which GPU a particular
message is being printed for and that is undesirable because it
complicates debugging efforts. Also, the new macros allow us to enable
logging for particular parts of the codebase more selectively (since we
no longer need to throw everything at DRM_DEBUG_KMS()). So, for the
reasons outlined above we should switch to the new macros.
We can accomplish this by using the existing DC_LOGGER code to pass
around the relevant `struct drm_device` which will be fed to the new
macros in logger_types.h. Also, we must get rid of all instances of the
DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use
the DC logger there and we can simply refer to the macros directly
there instead.

[Why]
There is a race condition between x86 and dmcub fw when attempting to exit
IPS2. Scenarios including exiting IPS2 before IPS2 has been entered. This
can cause unexpected hang when DMCUB attempt to exit while PMFW still
tries to enter IPS2.
[How]
A new design has been introduced to remove race conditions and improve the
handshake between x86 and DMCUB. An AON scratch register is borrowed from
PMFW to determine whether DMCUB has committed to IPS entry or not.
In the case when dmcub has committed IPS entry, x86 must poll until an exit
event occurred either from DMCUB(IPS1) or PMFW(IPS2). x86 will wait
upperbound of evaluation and IPS entry time to ensure IPS2 exit event has
been sent to PMFW.

commit minimal transition state would update current

new state, we will skip committing the full new state.

actaul currents state. Only skip full commit when
