Raspberry Pi's firmware offers and interface though which update it's performance requirements. It allows us to request for specific runtime frequencies, which the firmware might or might not respect, depending on the firmware configuration and thermals. As the maximum and minimum frequencies are configurable in the firmware there is no way to know in advance their values. So the Raspberry Pi cpufreq driver queries them, builds an opp frequency table to then launch cpufreq-dt. Also, as the firmware interface might be configured as a module, making the cpu clock unavailable during init, this implements a full fledged driver, as opposed to most drivers registering cpufreq-dt, which only make use of an init routine.
