When only that slow-clock is available, some peripherals lose functionality. Many can't issue wakeup events unless faster clocks are available. Some lose their operating state and need to be completely re-initialized. config AT91_TIMER_HZ int "Kernel HZ (jiffies per second)" range 32 1024 depends on ARCH_AT91 default "128" if SOC_AT91RM9200 default "100" help On AT91rm9200 chips where you're using a system clock derived from the 32768 Hz hardware clock, this tick rate should divide it exactly: use a power-of-two value, such as 128 or 256, to reduce timing errors caused by rounding. On AT91sam926x chips, or otherwise when using a higher precision system clock (of at least several MHz), rounding is less of a problem so it can be safer to use a decimal values like 100. endmenu endif
