modulename: mediatek-cpufreq-hw.ko

configname: CONFIG_ARM_MEDIATEK_CPUFREQ_HW

Linux Kernel Configuration

└─>MediaTek CPUFreq HW driver
In linux kernel since version 5.2 (release Date: 2019-07-07)  
Support for the CPUFreq HW driver.
Some MediaTek chipsets have a HW engine to offload the steps
necessary for changing the frequency of the CPUs. Firmware loaded
in this engine exposes a programming interface to the OS.
The driver implements the cpufreq interface for this HW engine.
Say Y if you want to support CPUFreq HW.
