This patch series introduces the Qualcomm SCMI Vendor protocol and adds a client driver that interacts with the vendor protocol and passes on the required tuneables to start various features running on the SCMI controller. The series specifically enables (LLCC/DDR) dvfs on X1E80100 SoC by passing several tuneables including the IPM ratio (Instructions Per Miss), cpu frequency to memory/bus frequency tables, CPU mapping to the vendor protocol which in turn will enable the memory latency governor running on the SCMI controller.
