This 8 is called Operating Performance Point or OPP. The actual definitions 9 of OPP varies over silicon within the same family of devices. 10 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. 14 For more information, read <file:Documentation/power/opp.rst> 15
