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. > > Dave > > -- > http://www.codemonkey.org.uk
