The intention here is stop the cpufreq governor and then to set the cpus to

The .suspend callback of the driver is not called during reboot/kexec.
So we need an explicit reboot notifier to call cpufreq-suspend() to
suffice the requirement.

Hi Shilpa,

No, we can't allow any platform driver to misuse cpufreq_suspend().
Platform drivers aren't *allowed* to call this routine.

Now the deal is how do we move to nominal frequency on reboot..
@Rafael: Any suggestions? How do we ensure that governors
are stopped on these notifiers, or if there is some other solution here?
