31846fd5c6bSWill Deacon	  executing the wfe instruction at a frequency represented as a
31946fd5c6bSWill Deacon	  power-of-2 divisor of the clock rate. The behaviour can also be
32046fd5c6bSWill Deacon	  overridden on the command line using the
32146fd5c6bSWill Deacon	  clocksource.arm_arch_timer.evtstream parameter.
322037f6377SWill Deacon	  The main use of the event stream is wfe-based timeouts of userspace
323037f6377SWill Deacon	  locking implementations. It might also be useful for imposing timeout
324037f6377SWill Deacon	  on wfe to safeguard against any programming errors in case an expected
325037f6377SWill Deacon	  event is not generated.
326037f6377SWill Deacon	  This must be disabled for hardware validation purposes to detect any
327037f6377SWill Deacon	  hardware anomalies of missing events.
