Gen9 hardware supports HDMI2.0 through LSPCON chips. Extending HDR
support for MCA and Parade LSPCON based GEN9 devices.
SOC will drive LSPCON as DP and send HDR metadata as standard
DP SDP packets. LSPCON will be set to operate in PCON mode,
will receive the metadata and create Dynamic Range and
Mastering Infoframe (DRM packets) and send it to HDR capable
HDMI sink devices.
v2: Fixed Ville's review comments. Suppressed some warnings.
Patch 8 of the series is marked "Not for Merge" and is just for
reference to userspace people to incorporate in order to support
10bit content with 4K@60 resolutions.
v3: Added Infoframe readout support for DRM infoframes.
Addressed Jani Nikula's review comments.
Note: Patch 8 of the series is for reference to userspace, not to be
merged to driver.
