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
