This enables the CPUfreq driver for the Samsung S3C24XX family
of CPUs.
For details, take a look at <file:Documentation/cpu-freq>.
If in doubt, say N.

depends on CPU_FREQ_S3C24XX && EXPERIMENTAL
help
Compile in support for changing the PLL frequency from the
S3C24XX series CPUfreq driver. The PLL takes time to settle
after a frequency change, so by default it is not enabled.
This also means that the PLL tables for the selected CPU(s) will
be built which may increase the size of the kernel image.
