Ok, let's reword my sentence. The cpufreq interface does not support
voltage as a parameter which is needed on platforms where you need
to do more than infer the correct voltage from the requested cpu
frequency. Or something like that. I wasn't challenging the
existing x86 cpufreq drivers, but the omap cpufreq driver does not
support voltage scaling.
