-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.
