[PATCH v9 00/12] Panel replay selective update support

[Jouni Högander]

This patch set is implementing panel replay selective update support
for Intel hardware.

v9:
  - do not add has_psr check into psr2 case in intel_dp_compute_vsc_sdp
  - use drm_dp_dpcd_readb instead of drm_dp_dpcd_read in intel_dp_get_su_capability
  - ensure intel_dp_get_su_capability returns 0 if drm_dp_dpcd_readb fails
v8:
  - use correct offset for DP_PANEL_PANEL_REPLAY_CAPABILITY
v7:
  - use always vsc revision 0x6 for Panel Replay
v6:
  - fixes split to separate patch set
v5:
  - do not use PSR2_STATUS for PSR1
v4:
  - do not rename intel_psr_enabled
  - do not add sel_update_et_enabled into struct intel_psr
v3:
  - do not disable panel replay by default
  - set has_psr for panel replay as well
  - enable sink before link training
  - do not apply all PSR workarounds for panel replay
  - do not write/read registers/bits not applicable for panel replay
  - use psr bit definitions in granularity configuration as well
  - goto unsupported instead of return when global enabled check fails
  - update module parameter descriptions.
v2:
  - make psr pause/resume to work for panel replay as well
