This series fixes issues faced when an HDMI2.1 sink that does not
support DSC is connected via HDMI2.1PCON. It also includes other minor
HDMI2.1 PCON fixes/refactoring.

Patch 1-2 Have minor fixes/cleanups.
Patch 3-6 Pull the decision making to use DFP conversion capabilities
for every mode during compute config, instead of having that decision
during DP initializing phase.
Patch 7-8 Calculate the max BPC that can be sufficient with either
RGB or YCbcr420 format for the maximum FRL rate supported.

Rev2: Split the refactoring of DFP RG->YCBCR conversion into smaller
patches, as suggested by Jani N.
Also dropped the unnecessary helper for DSC1.2 support for HDMI2.1 DFP.

Rev3: As suggested by Ville, added new member sink_format to store the
final format that the sink will be using, which might be different
than the output format, and thus might need color/format conversion
performed by the PCON.

Ankit Nautiyal (8):
  drm/i915/dp: Reset frl trained flag before restarting FRL training
  drm/i915/dp: Remove whitespace at the end of function.
  drm/i915/display: Add new member to configure PCON color conversion
  drm/i915/display: Add new member in intel_dp to store ycbcr420
    passthrough cap
  drm/i915/dp: Use sink_format in dp_is_ycbcr420
  drm/i915/dp: Replace intel_dp.dfp members with the new crtc_state
    sink_format
  drm/i915/dp: Handle BPP where HDMI2.1 DFP doesn't support DSC
  drm/i915/dp: Fix FRL BW check for HDMI2.1 DFP
