4a36fcbaec drm/amd/display: correct stream LTE_340MCSC_SCRAMBLE value
[Why]
HDMI 2.0 requires scrambling under specific conditions. We refer to
stream property LTE_340MCSC_SCRAMBLE to determine whether en/dis
scrambling.
While creating stream for sink, we setup LTE_340MCSC_SCRAMBLE by
referring to edid_caps. However, dm_helpers_parse_edid_caps()
doesn't construct HDMI Forum block data for edid_caps.
Moreover, fill_stream_properties_from_drm_display_mode() aslo
unconsciously clear the LTE_340MCSC_SCRAMBLE flag.

[How]
Drm already provides drm_display_info to refer HDMI Forum vsdb info.
Set stream LTE_340MCSC_SCRAMBLE by drm_display_info and remove
memset in fill_stream_properties_from_drm_display_mode()

d832fc3b18 drm/amd/display: build up VSIF infopacket
[Why]
Didn't send VSIF infopacket when it's 4k mode defined in HDMI 1.4b.
For HDMI 1.4b, While displaying 4k modes, it should send VSP.

[How]
Call mod_build_hf_vsif_infopacket() function to build info frame
and send it.

1cb1d47741 drm/amd/display: Correct values in AVI infoframe
[Why]
While displaying 4k modes defined in HDMI1.4b, should set VIC to 0
and use VSP HDMI_VIC to indicate the mode.

[How]
Use functions defined in drm to set up the VIC correspondingly.

90d268741f drm/amd/display: Added pixel dynamic expansion control.
[Why]
To compare the crc of the framebuffer data at input of
display pipeline with the crc of the otg, we need to
disable pixel formatter's dynamic expansion feature during
crc capture and keep it enable in the normal operation.

[HOW]
Expose a new interface in DM and dc for pixel formatter
(fmt dynamic bitdepth expansion control). Interface control
the FMT_DYNAMIC_EXP_EN  bit, during crc capture keep
it disabled.

[Why]
We need to manage the content protection property changes for
different usecase, once cp is DESIRED we need to maintain the
ENABLED/DESIRED status for different cases.

[How]
1. Attach the content_protection property

2. HDCP enable (UNDESIRED -> DESIRED)
	call into the module with the correct parameters to start
	hdcp. Set cp to ENABLED

3. HDCP disable (ENABLED -> UNDESIRED)
	Call the module to disable hdcp.

3. Handle Special cases	(Hotplug, S3, headless S3, DPMS)
	If already ENABLED: set to DESIRED on unplug/suspend/dpms,
	and disable hdcp

	Then on plugin/resume/dpms: enable HDCP

2ad0cdf9e2 drm/amd/display: set minimum abm backlight level
[Why]
A lot of the time, the backlight characteristic curve maps min backlight
to a non-zero value.
But there are cases where we want the curve to intersect at 0.
In this scenario even if OS never asks to set 0% backlight, the ABM
reduction can result in backlight being lowered close to 0.
This particularly can cause problems in some LED drivers, and in
general just looks like backlight is completely off.

[How]
Add default cap to disallow backlight from dropping below 1%
even after ABM reduction is applied.

452575c570 drm/amd/display: Lock the CRTC when setting CRC source
[Why]
We need to ensure that we're holding the lock on the CRTC when setting
the CRC source since we're modifying the CRTC state directly.

We also need to wait for any outstanding non-blocking commits to finish
so they aren't reading state that's potentially being modified -
non-blocking commits don't hold the CRTC lock while doing commit tail
work.

[How]
Lock the CRTC using its mutex. While holding the lock check if there's
any commit active on the CRTC - if there is, it's non-blocking and
we should wait until it's finished by waiting for hw_done to be
signaled since that's the last point where we touch CRTC state.

57638021b7 drm/amd/display: Split out DC programming for CRC capture
[Why]
Calling amdgpu_dm_crtc_set_crc_source in amdgpu_dm directly has the
consequence of adding additional vblank references or starting DPRX
CRC capture more than once without calling stop first.

Vblank references for CRC capture should be managed entirely by opening
and closing the CRC file from userspace.

Stream state also shouldn't be required on the CRC so we can close the
file after the CRTC has been disabled.

[How]
Do DC programming required for configuring CRC capture separately from
setting the source. Whenever we re-enable or reset a CRC this
programming should be reapplied.

CRC vblank reference handling in amdgpu_dm can be entirely dropped after
this.

Stream state also no longer needs to be required since we can just defer
the programming to when the stream is actually enabled.
