0080 The Smart Voltage Scaling(SVS) engine is a piece of hardware
0081 which has several controllers(banks) for calculating suitable
0082 voltage to different power domains(CPU/GPU/CCI) according to
0083 chip process corner, temperatures and other factors. Then DVFS
0084 driver could apply SVS bank voltage to PMIC/Buck.
