d61e4ba33e drm/amd/display: do not change pipe split policy for RV2
[Why]
RV2 do not change pipe split policy in the
minimal pipe split transition state.
This will unblock mode support on some
parts that limit to DPM0 for power reason.

[How]
Do not change pipe split policy in the
minimal pipe split transition state to
allow 4k multi display configs to be
supported at DPM0.

bf0dec4604 drm/amd/display: Expand documentation for timing
The timing programming inside DCN is far from trivial, it has multiple
parameters associated with that, and the lack of documentation does not
help comprehend this already complicated topic. This commit tries to
improve this situation by expanding the documentation of dc_crtc_timing
and the VTG program function.

e0df49b304 drm/amd/display: reverted limiting vscsdp_for_colorimetry and ARGB16161616 pixel format addition
[WHY]
Limiting vscsdp_for_colorimetry for YCbCr420/BT2020 resulted in red/green
point failures in HDR10 DTN tests. The re-implementation of ARGB16161616
was to fix this however it did not actually fix this issue but a side effect of the
issue.

[HOW]
Change ARGB16161616 pixel format to 26.

14eb72ff58 drm/amd/display: Exit SubVP if MPO in use
[Description]
Exit SubVP if MPO is in use since SubVP + MPO together is not supported.
- Don't add SubVP at validation time if we see MPO is in use

Issues fixed in the SubVP / MPO transition:
1. Enable phantom pipes in post unlock function to prevent underflow
when an active pipe is being transitioned to be a phantom pipe (VTG
updates take place right away). Also must wait for VUPDATE of the main
pipe to complete first

2. Don't wait for MPCC idle when transitioning a phantom pipe to an
actual pipe. MPCC_STATUS is never asserted due to OTG being off for
phantom pipes

3. When transitioning an active pipe to phantom, program DET right away
(same as disabling the pipe) or the DET update will only take when
the phantom pipe is enabled which can cause DET allocation errors.

4. For K1/K2 programming of phantom pipes, use same settings as the
main pipe. Also don't program K1 / K2 = 0xF ever since the field is only
1 / 2 bits wide.

76818cdd11 drm/amd/display: add Coverage blend mode for overlay plane
According to the KMS man page, there is a
"Coverage" alpha blend mode that assumes the
pixel color values have NOT been pre-multiplied
and will be done when the actual blending to
the background color values happens.

Previously, this mode hasn't been enabled
in our driver and it was assumed that all
normal overlay planes are pre-multiplied
by default.

When a 3rd party app is used to input a image
in a specific format, e.g. PNG, as a source
of a overlay plane to blend with the background
primary plane, the pixel color values are not
pre-multiplied. So by adding "Coverage" blend
mode, our driver will support those cases.

Issue fixed: Overlay plane alpha channel blending is incorrect
Issue tracker: https://gitlab.freedesktop.org/drm/amd/-/issues/1769

Reference:
https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#plane-composition-properties

Adding Coverage support also enables IGT
kms_plane_alpha_blend Coverage subtests:
1. coverage-7efc
2. coverage-vs-premult-vs-constant

Changes
1. Add DRM_MODE_BLEND_COVERAGE blend mode capability
2. Add "pre_multiplied_alpha" flag for Coverage case
3. Read the correct flag and set the DCN MPCC
pre_multiplied register bit (only on overlay plane)

da8c25929b drm/amd/display: Fix crash on setting VRR with no display connected
[HOW&WHY]
VRR was getting set at the same time
the timing generator would be null when there was no display
connected. Added null check to the timing generator variable
so it does not get referenced if it is null.

2513ed4f93 drm/amd/display: do not wait for mpc idle if tg is disabled
[Why]
When booting, the driver waits for the MPC idle bit to be set as part of
pipe initialization. However, on some systems this occurs before OTG is
enabled, and since the MPC idle bit won't be set until the vupdate
signal occurs (which requires OTG to be enabled), this never happens and
the wait times out. This can add hundreds of milliseconds to the boot
time.

[How]
Do not wait for mpc idle if tg is disabled

67229b27ed drm/amd/display: don't ignore alpha property on pre-multiplied mode
"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as
documented in supported_modes of drm_plane_create_blend_mode_property():
https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c

In this mode, both 'pixel alpha' and 'plane alpha' participate in the
calculation, as described by the pixel blend mode formula in KMS/DRM
documentation:

out.rgb = plane_alpha * fg.rgb +
          (1 - (plane_alpha * fg.alpha)) * bg.rgb

Considering the blend config mechanisms we have in the driver so far,
the alpha mode that better fits this blend mode is the
_PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain
is the plane alpha (global_alpha).

With this change, alpha property stops to be ignored. It also addresses
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1734

v2:
 * keep the 8-bit value for global_alpha_value (Nicholas)
 * correct the logical ordering for combined global gain (Nicholas)
 * apply to dcn10 too (Nicholas)

384bd90d1c drm/amd/display: Enable power gating before init_pipes
[Why]
In init_hw() we call init_pipes() before enabling power gating.
init_pipes() tries to power gate dsc but it may fail because
required force-ons are not released yet.
As a result with dsc config the following errors observed on resume:
"REG_WAIT timeout 1us * 1000 tries - dcn20_dsc_pg_control"
"REG_WAIT timeout 1us * 1000 tries - dcn20_dpp_pg_control"
"REG_WAIT timeout 1us * 1000 tries - dcn20_hubp_pg_control"

Move enable_power_gating_plane() before init_pipes() in init_hw()
