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. Huacai Chen(2): LoongArch: Add architectural preparation for CPUFreq. cpufreq: Add Loongson-3 CPUFreq driver support.
