CONFIG_CLOCK_FREQ: Set the core clock frequency

General informations

The Linux kernel configuration item CONFIG_CLOCK_FREQ has multiple definitions:

Set the core clock frequency found in arch/m68k/Kconfig.cpu

The configuration item CONFIG_CLOCK_FREQ:

Help text

Define the CPU clock frequency in use. This is the core clock frequency, it may or may not be the same as the external clock crystal fitted to your board. Some processors have an internal PLL and can have their frequency programmed at run time, others use internal dividers. In general the kernel won't setup a PLL if it is fitted (there are some exceptions). This value will be specific to the exact CPU that you are using.
