Subject: [PATCH 0/2] LoongArch: Add Loongson-3 CPUFreq driver support

This series add architectural preparation and CPUFreq driver for
Loongson-3 (based on LoongArch).

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.
