+description:
+ Texas Instruments SmartReflex is an on-chip adaptive power management
+ technology integrated into TI's OMAP and other SoCs. It dynamically
+ adjusts voltage and frequency for different chip domains in real time
+ to compensate for process, voltage, and temperature (PVT) variations.
+ Dedicated hardware sensors and control logic continuously monitor
+ conditions and apply the lowest safe voltage for the required performance
+ level.
