The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a Hardware module used to collect all the requests from both software and the various remote processors embedded into the SoC and decide about a minimum operating voltage and a minimum DRAM frequency to fulfill those requests in an effort to provide the best achievable performance per watt. This hardware IP is capable of transparently performing direct register R/W on all of the DVFSRC-controlled regulators and SoC bandwidth knobs. This driver includes support for MT8183, MT8192 and MT8195.
