They are not interchangeable. dmub aux transaction could pass if happens eDP link_index gets the same value as vbios ddc_channel, e.g., ddc_channel = 1, link_index = 1 if they gets different, e.g., ddc_channel = 2, link_index = 0, overwrite ddc_channel with link_index will have wrong ddc channel being used for aux transaction in dmub PSR, cause aux transaction soft hang.

2022-07-05drm/amd/display: Maintain consistent mode of operation during encoder assignmentJimmy Kizito4-5/+44
[Why] While applying a state to hardware, there is a transition period where the back-end is reset using the old state; then enabled using the new state. Generally, the link encoder configuration module queries stream-to-encoder assignments in either the new or old state based on a mode variable. During the transition there is a need to query both states, however toggling this mode variable can lead to incorrect programming of encoders. [How] - Add new function to explicity query stream-to-encoder assignment in the current state rather than intermittently switch the mode of operation of the link encoder assignment module. - Add additional checks for encoder assignment defects. - Explicitly reset the mode of operation if application of state to hardware ends prematurely.
