[PATCH v3 00/12] Panel Replay + Adaptive sync

[Jouni Högander]

This patch set is adding missing configuration to have Panel Replay
and Adaptive Sync enabled simultaneously. Also some issues identified
while debugging are fixed:

1. Source PORT ALPM configuration has to made during modeset.
2. PHY_CMN1_CONTROL is not written according to HAS document
3. Wrong register field definitions for PORT_ALPM_LFPS_CTL.

Patches are tested on LunarLake and PantheLake using our reference panel supporting
Adaptive Sync and Panel Replay.

EMP_AS_SDP_TL is currently missing completely from drm-tip. There is a patch for that which is needed if testing these patches:

Otherwise "PSR idle timeout" errors are seen while testing.

v3:
  - comment about DP2.1 corrected as DP2.1a
  - referring patch removed from commit message
v2:
  - rework Panel Replay DPCD register definitions
  - do not use hardcoded indices while accessing intel_dp->pr_dpcd
  - ensure ALPM registers are not written on platform where they do
    not exist
  - remove kerneldoc comments
