| 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. |
| 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. |
