Is it ok for you if we go further with this patch series and continue talki= ng 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.
