| config AT91_SLOW_CLOCK |

| depends on SUSPEND |
| help |
| Select this if you want Suspend-to-RAM to save the most power |
| possible (without powering off the CPU) by disabling the PLLs |
| and main oscillator so that only the 32 KiHz clock is available. |
| |
| 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. |

| 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. |
