Ah, sorry.  I get this one mixed up with "Add support for the PolarFire 
SoC system controller", which I also had in my inbox because I wanted to 
make sure it didn't get dropped.  I guess I just didn't read the whole 
title and dropped this v4 because I thought the v6 was a newer version 
of the same patch set.

This is now on for-next.

Thanks!
