Applied, thanks (though checking return codes would be nice).
Ideally you'd be able to enable the clocks only when needed at runtime
though the power savings would doubtless be very small, pm_runtime
callbacks might be helpful. Having the clocks present on PowerPC (even
if just dummy) so we don't have the conditional code would also be nice.
