OPP library provides a set of helper functions to organize and query the OPP
information. The library is located in drivers/base/power/opp.c and the header
-is located in include/linux/opp.h. OPP library can be enabled by enabling
+is located in include/linux/pm_opp.h. OPP library can be enabled by enabling
CONFIG_PM_OPP from power management menuconfig menu. OPP library depends on
CONFIG_PM as certain SoCs such as Texas Instrument's OMAP framework allows to
optionally boot at a certain OPP without needing cpufreq.
