    +title: MediaTek dynamic voltage and frequency scaling resource collector (DVFSRC)
    +
    +description: |
    + The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a
    + HW module which is used to collect all the requests from both software and
    + hardware and turn into the decision of minimum operating voltage and minimum
    + DRAM frequency to fulfill those requests.

    + The DVFSRC regulator is modelled as a subdevice of the DVFSRC.
    + Because DVFSRC can request power directly via register read/write, likes
    + vcore which is a core power of mt8183. As such, the DVFSRC regulator
    + requires that DVFSRC nodes be present.
