Hi, This is a try to have some simple DVFS (Dynamic Voltage and Frequency Scaling) support for GK20A. Instead of relying on other existing frequency scaling framework, we create a simple subdev in Nouveau for the same purpose. That's because we don't want to make the DVFS implementation for GK20A far more than enough in the beginning and hinder the implementation for dGPU in the future.
