Currently the HDMI2.1 PCON creates the default AVI infoframes
based on DP VSC packets. For better control, source can write the
AVI infoframe and send as DP GMP SDP packet. The PCON unpacks the
AVI infoframe encapsulated in DP GMP SDP packet, and forwards the
same to HDMI2.1.
This series is continuation of the RFC :
https://patchwork.freedesktop.org/series/85073/
It adds support for writing infoframe for HDMI2.1 sink, connected via
HDMI2.1 PCON. This series also adds AVI infoframe version 3,
which is requied for new modes supported by HDMI2.1.

Ankit Nautiyal (3):
  video/hdmi: Separate function for unpacking AVI Infoframe Data
  video/hdmi: Add AVI version 3 defined in CTA-861-G
  drm/drm_edid: Avoid CEA VICs meant for HDMI2.1 in AVI Infoframes for
    older HDMI sinks.

Swati Sharma (3):
  drm/i915: Export intel_hdmi_compute_avi_infoframe()
  drm/i915: Sending AVI infoframe through GMP DIP
  drm/i915: Implement readout for AVI infoframe SDP
