+ ---help---
+ SOCs have a standard set of tuples consisting of frequency and
+ voltage pairs that the device will support per voltage domain. This
+ is called Operating Performance Point or OPP. The actual definitions
+ of OPP varies over silicon within the same family of devices.
+
+ OPP layer organizes the data internally using device pointers
+ representing individual voltage domains and provides SOC
+ implementations a ready to use framework to manage OPPs.
