+         Select this option if you want to disable continuous timer ticks
+         and have them programmed to occur as required. This option saves
+         power as the system can remain in idle state for longer.
+
+         By default dynamic tick is disabled during the boot, and can be
+         manually enabled with:
+
+           echo 1 > /sys/devices/system/timer/timer0/dyn_tick
+
+         Alternatively, if you want dynamic tick automatically enabled
+         during boot, pass "dyntick=enable" via the kernel command string.
+
+         Please note that dynamic tick may affect the accuracy of
+         timekeeping on some platforms depending on the implementation.
+         Currently at least OMAP platform is known to have accurate
+         timekeeping with dynamic tick.
