30       For example, the CPU clock frequency is 108MHz, and the system timer
31       uses 27MHz, which is the CPU clock divided by 4.
32       In this case, the CPU clock frequency is defined in the CPU node

44       Setting clk-divider to 2 specifies the system timer uses the clock
45       that CPU clock frequency divided by (2^2=)4, or 27MHz.
