[PATCH 0/3] Enable Adaptive Sync SDP Support for DP

[Mitul Golani]

An Adaptive Sync SDP allows a DP protocol converter to
forward Adaptive Sync video with minimal buffering overhead
within the converter. An Adaptive-Sync-capable DP protocol
converter indicates its support by setting the related bit
in the DPCD register.

Computes AS SDP values based on the display configuration,
ensuring proper handling of Variable Refresh Rate (VRR)
in the context of Adaptive Sync.

--v2:
- Update logging to Patch-1
- use as_sdp instead of async
- Put definitions to correct placeholders from where it is defined.
- Update member types of as_sdp for uniformity.
- Correct use of REG_BIT and REG_GENMASK.
- Remove unrelated comments and changes.
- Correct code indents.
- separate out patch changes for intel_read/write_dp_sdp.

  drm: Add Adaptive Sync SDP logging
  drm/i915/dp: Add Read/Write support for Adaptive Sync SDP
  drm/i915/display: Compute and Enable AS SDP
