Hi Rob,

You're speaking to the person who was perfectly happy with 
"polarfire-soc" when I wrote the binding last year, but I was asked to 
change it in order avoid having a different compatible string in the 
device tree for the soc and in the binding for a device that only exists 
in that soc.

If the v2 was a complete rename from "polarfire-soc-*" to "mpfs-*", 
including the file name - as opposed to an addition and I changed the 
commit message to the following would you be happier with the patch?

Thanks,
Conor.
