Some of LoongArch processors support DVFS, their IOCSR.FEATURES has IOCSRF_FREQSCALE set. And they has a micro-core in the package called SMC (System Management Controller) to scale frequency, voltage, etc. V1 -> V2: 1, Use module_platform_driver() instead of module_init()/module_exit(); 2, Move the lock protection into do_service_request(); 3, Add light-weight hotplug support with help of online()/offline() callbacks; 4, Simplify loongson3_freq_data by removing cur_cpu_freq; 5, Remove unneeded cpu_online() checking. Huacai Chen(2): LoongArch: Add architectural preparation for CPUFreq. cpufreq: Add Loongson-3 CPUFreq driver support. Signed-off-by: Huacai Chen --- 2.27.0
