How to change any frequency above 1017600Hz on-the-fly

echo 'c1536000 1593600 1325' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

"c" means CHANGE

"1536000" old frequency

"1593600" new frequency (unlimited)

"1325" voltage (limited to 1500mV)

How to set max frequency on-the-fly

echo 'm1593600 1350' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

"m" means max frequency

1593600 is max frequency (no limitation)

1350 is voltage for this frequency (maximum is limited to 1500mV)
