b1a98cf89a drm/amd/display: Wrong colorimetry workaround
[Why]
For FreeSync HDR, native color space flag in AMD VSIF(BT.709) should be
used when intepreting content and color space flag in VSC or AVI
infoFrame should be ignored. However, it turned out some userspace
application still use color flag in VSC or AVI infoFrame which is
incorrect.

[How]
Transfer function is used when building the VSC and AVI infoFrame. Set
colorimetry to BT.709 when all the following match:

1. Pixel format is YCbCr;
2. In FreeSync 2 HDR, color is COLOR_SPACE_2020_YCBCR;
3. Transfer function is TRANSFER_FUNC_GAMMA_22;

75f77aafe2 drm/amd/display: Send H14b-VSIF specified in HDMI
[Why]
Current function excludes the logic to generate H14b-VSIF. Now it
constructs HF-VSIF only and causes HDMI compliace test fail.

[How]
According to HDMI spec, source devices shall utilize the H14b-VSIF
whenever the signaling capabilities of the H14b-VSIF allow this.

Here keep the logic for HF-VSIF and add H14b-VSIF construction part.

cdca3f218d drm/amd/display: move location of dmub_srv.h file
[Why]
Make a separation of what belongs in the differen dmub
headers

dmub_srv.h is for exposing dmub srv interface to rest of
driver.

other headers inside dmub/inc exposes cmds and definitions
that are owned by the firmware

[How]
keep firmware owned definitions in dmub/inc

move stuff that is purely driver interface headers to dmub/
since those are interface calls that are defined for rest of
driver to use

1cfbbddead drm/amd/display: add addition dc type to translate to dmub fw type
[Why]
For a type like PSR version, it makes sense for most of the code
to include a dc type, instead of having this a fw type define since
this is a capability and type exposed by dc.

Especially if it doesn't even need to communicate with the fw.

The code that is packing the firmware command message
should be the one who needs to translate the psr version
into a command that the firmware understands.

[How]
Add a dc_psr_version enum.

d1ebfdd8d0 drm/amd/display: Unify psr feature flags
[Why]
As it stands, psr has feature flags in dm, stream, and link. Most are
not defined well enough, and different dm layers have different uses for
these same flags.

[How]
We define a new structure called psr_settings in dc_link that will hold
the following psr feature flags:

psr_feature_enable - psr is supported
psr_allow_active - psr is currently active
psr_version - internal psr version supported
psr_frame_capture_indication_req
psr_sdp_transmit_line_num_deadline
The last two flags were moved out of the power module
for the purposes of consolidating psr flags.
Their use is already well-defined.

Psr caps reported by sink will also be stored in dc_link,
in dpcd_caps.psr_caps.

5ed78cd69a drm/amd/display: set MSA MISC1 bit 6 while sending colorimetry in VSC SDP
[Why]
It is confusing to sinks if we send VSC SDP only on some format. Today we
signal colorimetry format using MSA while in formats like sRGB.
But when we switch to BT2020 we set the bit to ignore MSA  colorimetry and
instead use the colorimetry information in the VSC SDP.

But if sink supports signaling of colorimetry via VSC SDP we should always
set the MSA MISC1 bit 6, instead of doing so selectively.

[How]
If sink supports signaling of colorimetry via VSC SDP, and we are sending
the colorimetry info via VSC SDP with packet revision 05h, then always
set MSA MISC1 bit 6.
