Adding new working point - frequency in linux

Deciding what frequency within the CPUfreq policy should be used is achieved using "cpufreq governors".
Inside the CPUFreq we can find:
# ls /sys/devices/system/cpu/cpu1/cpufreq/
affected_cpus
related_cpus
scaling_max_freq
bios_limit
scaling_available_frequencies
scaling_min_freq
cpuinfo_cur_freq
scaling_available_governors
scaling_setspeed
cpuinfo_max_freq
scaling_cur_freq
stats
cpuinfo_min_freq
scaling_driver
cpuinfo_transition_latency
scaling_governor
scaling_available_frequencies shows all available frequencies, for example:
# cat scaling_available_frequencies
2997000 2664000 2331000 1998000
How can I add more frequency values?
Can anyone please help me to add additional intermediate frequency values?
Is that can be done in Linux config (kernel compilation) or in the cpufreq driver?
