2013-04-19 Thread Taras Kondratiuk
Using a "voltage tolerance" for doing DVFS is not a proper way. It leads to a few issues: - voltage is limited to a narrow range near OPP voltage, so other consumers of the same regulator can't set their own constraints if they don't overlap with this narrow range. No ganged rails :( - usually
