I thought one of the issues before dt was that clocks were in a global

take a tour through clkdev to educate myself.

There's both a global namespace and a device local namespace, the most
exact match is used - see the comment on clk_find().  Remember that in
the past clock implementations didn't have to use clkdev at all so the
implementations varied a lot (which is half the problem with drivers
now).  Lots of implementations just used global clock names and didn't
pay any attention to dev.
