[PATCH v5 05/19] drm/i915/psr: Add Panel Replay support to intel_psr2_config_et_valid

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Early Transport is possible and in our HW mandatory on eDP Panel
Replay. Add parameter to intel_psr2_config_et_valid to differentiate
validity check for Panel Replay.
