Aside from that question about the i2c bug these look good to me.  I don't see
any Ack/Review on the DT side of things, though.  If you want to take them
through a DT tree that's fine for me, I'll leave them in my inbox for now and
if nobody says anything I'll look a bit more and take them for 5.12.
