[PATCH 00/16] Enable Colorspace connector property in amdgpu

[Harry Wentland]

This patchset enables the DP and HDMI infoframe properties
in amdgpu.

The first two patches are not completely related to the rest. The
first patch allows for HDR_OUTPUT_METADATA with EOTFs that are
unknown in the kernel.

The second one prints a connector's max_bpc as part of the atomic
state debugfs print.

The following patches rework the connector colorspace code to
1) allow for easy printing of the colorspace in the drm_atomic
   state debugfs, and
2) allow drivers to specify the supported colorspaces on a
   connector.

The rest of the patches deal with the Colorspace enablement
in amdgpu.

Since the Colorspace property didn't have an IGT test I added
one to kms_hdr. The relevant patchset can be found on the IGT
mailing list or on
https://gitlab.freedesktop.org/hwentland/igt-gpu-tools/-/tree/hdr-colorimetry

Since I don't have a DP and HDMI analyzer I could not test this
end-to-end but someone will test it in the coming days. We'll
refrain from merging this until we can confirm the DP/HDMI analyzer
shows the correct infoframe.
