arm64: dts: sm8150: Optimize frequency tables and energy model
Each cluster's minimum frequency is now its most efficient frequency by ULPMark-CM [1] score (CoreMark [2] iterations per millijoule of energy) and the energy model has been recalculated to accomodate for the frequency changes. All measurements and tuning have been done for SM8150-AA (Snapdragon 855), but some accomodations have been made for SM8150-AC (Snapdragon 855+) as well. Inefficient intermediate frequencies have been removed for performance and power reasons. The maximum frequency for each cluster, however inefficient, has been retained for maximum peak performance. Efficient frequency selection has been performed based on ULPMark-CM scores (I/mJ) and manual discretion. Power and performance measurements were made using my freqbench [3] benchmark, which isolates, offlines, and disables the timer tick on test CPUs to maximize accuracy. Normalized DMIPS/MHz capacity scale values for each CPU have also been updated to reflect measurements. Instead of using DMIPS/MHz, we use CoreMarks/MHz (CoreMark iterations per second per MHz), which serves the same purpose. For each CPU, the final capacity-dmips-mhz value is the CM/MHz value of its maximum frequency normalized to SCHED_CAPACITY_SCALE (1024) for the fastest CPU on the system. All human-readable source data and energy model results are included below. All benchmark data, including the raw samples in machine-readable JSON format, can be found in the freqbench repository [4]. IF YOU HAVE SM8150-AC, replace the energy model with one created for the AC variant from below and remove the excess frequencies.
