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.
