Hi Blartlomiej, Thank you. I'll merge this into devfreq's for-next. Anyway, days ago, I had a short discussion with Chanwoo about providing some common interface for PPMU-like devices (sort of sub device of devfreq device) that provide usage statistics. At this stage, I roughly guess that such a device driver (or whatever entity it is) may be simply a helper for filling out the "get_dev_status" callback. It is because devfreq's PPMU usage is limited to getting get_dev_status(). As you had done something on PPMU, I guess you may have some idea on this.
