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