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