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.
