Actually it fails inside the function intel_dp_link_training_clock_reciovery() when it tries to write the TP1 and errors out saying "Failed to enable link training". Yes but it worked fine for DPCD reads over AUX, so that's why I am confused as to where we need to add the delay for the AUX reads? Also, shouldn't the spec for that specific panel or the eDP spec talk about how much delay should be given for the AUX read/writes? Any thoughts on double checking this in the spec?
