+title: MediaTek Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC)
+
+description:
+ 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.
