This patch set is implementing panel replay selective update support
for Intel hardware.
It is also fixing several exisiting issues in current panel replay implementation:
Several needed functions are not executed for panel replay
Ensure link training follows enabling panel replay on sink side
Do not update phy power state for panel replay.
Do not apply workarounds not applicable for panel replay
Do not write registers/bits not applicable for panel replay
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
