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

Message

Golani, Mitulkumar Ajitkumar Nov. 23, 2023, 2:02 p.m. UTC

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.
