I don't think there should be a new node to control the register; it should be done through the cpufreq mechanism. You can get a start by reading the cpufreq documentation, and then comparing it against the cpufreq code we currently have. I'm interested to discuss this more. I have been wanting this feature for a while; and even have written some code for it a couple of times, but I tend to get distracted too easily when it comes to hobby code. cheers, John
