228 config AT91_SLOW_CLOCK
229 bool "Suspend-to-RAM disables main oscillator"
232 Select this if you want Suspend-to-RAM to save the most power
233 possible (without powering off the CPU) by disabling the PLLs
234 and main oscillator so that only the 32 KiHz clock is available.
236 When only that slow-clock is available, some peripherals lose
237 functionality. Many can't issue wakeup events unless faster
238 clocks are available. Some lose their operating state and
239 need to be completely re-initialized.
242 int "Kernel HZ (jiffies per second)"
245 default "128" if ARCH_AT91RM9200
248 On AT91rm9200 chips where you're using a system clock derived
249 from the 32768 Hz hardware clock, this tick rate should divide
250 it exactly: use a power-of-two value, such as 128 or 256, to
251 reduce timing errors caused by rounding.
253 On AT91sam926x chips, or otherwise when using a higher precision
254 system clock (of at least several MHz), rounding is less of a
255 problem so it can be safer to use a decimal values like 100.
