I pulled this into clk-next but it didn't seem to get picked up by
linux-next in time for today's build. Let's test the next linux-next to
insure that the regressions are gone. If not then I'll likely need to
drop "clk: respect the clock dependencies in of_clk_init" from clk-next
for 3.15.

Regards,
Mike
