51c7e6ac24 drm/amd/display: revert "for FPO & SubVP/DRR config program vmin/max"
This reverts commit 6b2b782ad6.

The original commit causes issues with certain features when DRR is
disabled, need to revisit this change later after resolving issues with
new DRR policy.

For FPO and SubVP/DRR cases we need to ensure to program
OTG_V_TOTAL_MIN/MAX_SEL, otherwise stretching the vblank in FPO / SubVP
/ DRR cases will not have any effect and we could hit underflow /
corruption.

ade13d3fc0 drm/amd/display: Don't allow FPO if no planes
In DCN32/321 FPO uses per-pipe P-State force. If there is no plane, then
then HUBP is power gated, in which case any programming in HUBP has no
effect and the pipe is always asserting P-State allow. This is contrary
to what we want to happen for FPO (FW should moderate the P-State
assertion), so block FPO if there's no plane for the FPO pipe.

85fce15399 drm/amd/display: change static screen wait frame_count for ips
[Why]
the original wait for 2 static frames before enter static screen
was not good enough for IPS-enabled case since enter/exit takes more time.

Changed logic for hardcoded wait frame values.

012a04b1d6 drm/amd/display: Refactor phantom resource allocation
[WHY?]
Phantom streams and planes were previously not referenced explcitly on creation.

[HOW?]
To reduce memory management complexity, add an additional phantom streams and planes
reference into dc_state, and move mall_stream_config to stream_status inside
the state to make it safe to modify in shallow copies. Also consildates any logic
that is affected by this change to dc_state.

09a4ec5da9 drm/amd/display: Refactor dc_state interface
[WHY?]
Part of the dc_state interface that deals with adding streams and planes should
remain public, while others that deal with internal status' and subvp should be
private to DC.

[HOW?]
Move and rename the public functions to dc_state.h and private functions to
dc_state_priv.h. Also add some additional functions for extracting subvp meta
data from the state.

dd2c5fac91 drm/amd/display: Add ODM check during pipe split/merge validation
[why]
When querying DML for a vlevel after pipes have been split or merged the
ODM policy would revert to a default policy, which could cause the query
to use the incorrect ODM status. In this case ODM 2to1 was validated,
but the last DML query would assume no ODM and return the incorrect
vlevel.

[how]
Added ODM check to apply the correct ODM policy before querying DML.

8f3656ce65 drm/amd/display: Enable SubVP on 1080p60 displays
[Description]
- Previously SubVP would never be selected on 1080p60 displays because
  it has too much vactive margin. However, implement a change to allow
  it like how 1440p60 is allowed.
- Add a new struct such that we have a list of allowed modes for
  enabling subvp with vactive margin (currently 1080p60 and 1440p60)
- Also ensure to block drr + vblank cases to prevent unexpected
  enablement of new display configs
- Update SW cursor fallback for these new potential cases as well

3f3b08be58 drm/amd/display: Add z-state support policy for dcn35
[Why]
DML2 means that the dcn3x policy for calculating z-state support
no longer runs from validate_bandwidth.

This means we are unconditionally allowing Z8, the hardware default.

[How]
Port the policy over to DCN35, but with a few modifications:
- Don't use min_dst_y_next_start as a check for Z8/Z10 allow
- Add support for overriding the Z10 stutter period per ASIC
- Cleanup the code to make the policy assignment more clear
