drm/amd/display: Take full update path if number of planes changed

2023-06-30T17:12:16+00:00

[Description]
- A full update is required if the number of planes for a given
  stream changes
- The new fast update path only checked for stream and plane updates,
  but there could be a plane addition or removal without one of the
  stream and plane updates triggering a full update
- Add an explicit check for number of planes changing for a full update

drm/amd/display: For new fast update path, loop through each surface

2023-06-30T17:12:15+00:00

[Description]
- Previous implementation didn't consider multiple surfaces in a flip
- Loop through each surface in each flip to ensure the update path is
  correct

drm/amd/display: Limit new fast update path to addr and gamma / color

2023-06-30T17:12:15+00:00

[Description]
- We want to limit the new fast update path to address and gamma updates
  only.
- Add a check in dc_update_planes_and_stream to only take the new fast
  update path if we only have the specific fast updates defined.

drm/amd/display: Enable dc mode clock switching for DCN32x

2023-06-23T19:45:57+00:00

- DC mode clock switch interface was previously only executed
  for DCN303. Enable it for DCN32x so that the interface is called
  correctly
- Assign function pointers for DCN32x that are used in the dc mode
  interface
- Update the dc mode interface to work generically for each ASIC
- In update_clocks, make sure to consider softmax if we're in DC mode

drm/amd/display: disable seamless boot if force_odm_combine is enabled

2023-06-23T19:44:28+00:00

[Why & How]
Having seamless boot on while forcing debug option ODM combine 2 to 1
will cause some corruptions because of some missing programmings.

drm/amd/display: Clear update flags at end of flip

2023-06-23T19:42:21+00:00

Clear update flags so the next flip does not have any redundant
programming (if a subsequent flip does not have a stream or plane
update, the update flags are not cleared).

Condition for programming manually trigger used the wrong pipe (always
used top pipe instead of the one we are iterating through).
