CONFIG_PM_OPP: Operating Performance Point (OPP) Layer library

General informations

The Linux kernel configuration item CONFIG_PM_OPP has multiple definitions:

found in kernel/power/Kconfig

The configuration item CONFIG_PM_OPP:

Help text

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. For more information, read Documentation/power/opp.txt
