+title: Introduce SVS engine
+

+  - Kevin Hilman <khilman@kernel.org>

+
+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.
