[RFC PATCH] cpufreq: add support for HiSilicon SoC HIP09

2020-04-29 Thread Xiongfeng Wang
HiSilicon SoC has a separate System Control Processor(SCP) dedicated for clock frequency adjustment and has been using the cpufreq driver 'cppc-cpufreq'. New HiSilicon SoC HIP09 add support for CPU Boost, but ACPI CPPC doesn't support this. In HiSilicon SoC HIP09, each core has its own clock domain
