MT8183 supports CPU DVFS and CCI DVFS, and LITTLE cpus and CCI are in the same voltage domain.
So, this series is to add drivers to handle the voltage coupling between CPU and CCI DVFS.
For SVS support, need OPP_EVENT_ADJUST_VOLTAGE and corresponding reaction.
What is correct full word of SVS?
- S(?) VS (Voltage Scaling) ?
