+description: |+
+ The Smart Voltage Scaling(SVS) engine is a piece of hardware
+ which has several controllers(banks) for calculating suitable
+ voltage to different power domains(CPU/GPU/CCI) according to
+ chip process corner, temperatures and other factors. Then DVFS
+ driver could apply SVS bank voltage to PMIC/Buck.
