Subject: [PATCH] ARC: reset: remove the misleading v1 suffix all over
There is no plan yet to do a v2 board. And even if we were to do it only
some IPs would actually change, so it be best to add suffixes at that
point, not now !

P.S. Philip, if you and Eugeniy are OK, can this be please squashed with
his original patch since it has not yet been merged etc.
Thx,
