Hi Stephen, Thank you for the review.

Hi Dmitry, As discussed over a separate email, we will be exploring using the generic panel edp and aux bus after implementing the basic PSR feature. We are using a non-generic compatible string now because we enabled PSR with this. The changes from aux-bus and generic-edp may be intrusive for the dp driver and hence we want to explore it as a separate task/feature after the basic PSR feature.
