Ok. Well we're in rc1 right now, and so we're not merging new drivers
into mainline. I can merge the clk driver into clk-next, but you'll have
to wait for the stabilization period to end (approximately 6 or 7 weeks)
before this can get into the next kernel version. It will be in
linux-next much sooner of course.
