Link Off Between Active Frames, is a new feature for eDP that allows the panel to go to lower power state after transmission of data. This is a feature on top of ALPM, AS SDP. Add compute config during atomic-check phase. v1: RFC version. v2: Add separate flag for auxless-alpm. [Jani] v3: - intel_dp->lobf_supported replaced with crtc_state->has_lobf. [Jouni] - Add DISPLAY_VER() check. [Jouni] - Modify function name of get_aux_less_status. [Jani] v4: Add enum alpm_mode to hold the aux-wake/less capability. v5: Add alpm_dpcd to intel_dp and use aux_wake_supported()/ aux_less_wake_supported() instead of enum alpm_mode.
