179 config AT91_SLOW_CLOCK
180 bool "Suspend-to-RAM disables main oscillator"
184 Select this if you want Suspend-to-RAM to save the most power
185 possible (without powering off the CPU) by disabling the PLLs
186 and main oscillator so that only the 32 KiHz clock is available.
188 When only that slow-clock is available, some peripherals lose
189 functionality. Many can't issue wakeup events unless faster
190 clocks are available. Some lose their operating state and
191 need to be completely re-initialized.
194 int "Kernel HZ (jiffies per second)"
197 default "128" if SOC_AT91RM9200
200 On AT91rm9200 chips where you're using a system clock derived
201 from the 32768 Hz hardware clock, this tick rate should divide
202 it exactly: use a power-of-two value, such as 128 or 256, to
203 reduce timing errors caused by rounding.
205 On AT91sam926x chips, or otherwise when using a higher precision
206 system clock (of at least several MHz), rounding is less of a
207 problem so it can be safer to use a decimal values like 100.
