Thanks for the patches, but creating devfreq devices for each interconnect path seems odd to me - at least for consumers that already use a governor. So for DDR scaling for example, are you suggesting that we add a devfreq device from the cpufreq driver in order to scale the interconnect between CPU<->DDR? Also if the GPU is already using devfreq, should we add a devfreq per each interconnect path? What would be the benefit in this case - using different governors for bandwidth scaling maybe? Thanks, Georgi
