Is it ok for you if we go further with this patch series and continue talking
about PSE power domain alongside?
It should not be necessary to be supported with port priority as the two PSE
supported controller can behave autonomously on a power domain.
I hope I will have time in the project to add its support when we will have a
more precise idea of how.
