MT8173 is a ARMv8 based SoC with 2 clusters. All CPUs in a single cluster
share the same power and clock domain. This series tries to add cpufreq support
for MT8173 SoC by using DT based cpufreq driver. 

From v1 to v2:

1. Add intermediate frequency support in cpufreq-dt driver
2. Use voltage scaling code of cpufreq-dt for little cluster instead of
   implementaion in notifier of mtk-cpufreq driver
3. Code refinement for mtk-cpufreq driver

pi-cheng.chen (4):
  cpufreq-dt: add clock domain and intermediate frequency support
  cpufreq: dt-bindings: add bindings for mtk-cpufreq driver
  cpufreq: mediatek: add Mediatek cpufreq driver
  ARM64: dts: mediatek: add cpufreq dts for MT8173 SoC
