The slow clock always exists, selecting CONFIG_AT91_SLOW_CLOCK config is unnecessary for the suspend to memory mode. For this mode the master clock should always switch to the slow clock.

|
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.
