config AT91_SLOW_CLOCK
	bool "Suspend-to-RAM disables main oscillator"
	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.

       default "128" if SOC_AT91RM9200
       default "100"
       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.
