Subject: PM / AVS: SVS: Introduce SVS engine
Date: Tue, 30 Apr 2019 19:20:09 +0800 [thread overview]
Message-ID: <20190430112012.4514-1-roger.lu@mediatek.com> (raw)
The SVS (Smart Voltage Scaling) engine is a piece of hardware which is
used to calculate optimized voltage values of several power domains, e.g.
CPU/GPU/CCI, according to chip process corner, temperatures, and other
factors. Then DVFS driver could apply those optimized voltage values to
reduce power consumption.
