+description: |+
+ The 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.
