frequencies, a "frequency table" with some functions might assist in

some work of the processor driver. Such a "frequency table" consists

of an array of struct cpufreq_frequency_table entries, with any value in

"index" you want to use, and the corresponding frequency in

"driver_data" you want to use, and the corresponding frequency in
