Hi Dmitry, This patch contains the three features as following: 1. Use interconnect interface for controlling the clock instead of controlling it direclty 2. Use EMC_STAT instead of IMC_STAT 3. Change polling_interval and upthreshold for more fast responsiveness I think you need to make the separ

2020-10-26 Thread Dmitry Osipenko
External (EMC) and Internal Memory Controllers (IMC) have a nearly identical statistics gathering module. This patch switches driver to use EMC_STAT instead of IMC_STAT and adds device-tree support which brings ICC support and makes driver to use bandwidth OPPs defined in device-tree. The previous
