Don't have any intentions to halt this series anymore, I have
irritated you enough already :)

But, what about moving these bindings in something like a clock
driver?

@Mike: ?

I am asking because these really belong to the clock driver, as I
understood it from Mike. And clearly asked me to not take care of such
things in cpufreq core/drivers.

Another reason is that, later you will kill this driver one day and
use cpufreq-dt. And then you will be required to move these bindings
to a clock driver, as these will stay.
