This 77813dd6fSViresh Kumar is called Operating Performance Point or OPP. The actual definitions 87813dd6fSViresh Kumar of OPP varies over silicon within the same family of devices. 97813dd6fSViresh Kumar 107813dd6fSViresh Kumar OPP layer organizes the data internally using device pointers 117813dd6fSViresh Kumar representing individual voltage domains and provides SOC 127813dd6fSViresh Kumar implementations a ready to use framework to manage OPPs. 13151f4e2bSMauro Carvalho Chehab For more information, read <file:Documentation/power/opp.rst> 14
