The behaviour can also be	  overridden on the command line using the	  clocksource.arm_arch_timer.evtstream parameter.	  The main use of the event stream is wfe-based timeouts of userspace	  locking implementations. It might also be useful for imposing timeout	  on wfe to safeguard against any programming errors in case an expected	  event is not generated.	  This must be disabled for hardware validation purposes to detect any	  hardware anomalies of missing events. config ARM_ARCH_TIMER_OOL_WORKAROUND	bool config FSL_ERRATUM_A008585	bool "Workaround for Freescale/NXP Erratum A-008585"	default y	depends on ARM_ARCH_TIMER && ARM64	select ARM_ARCH_TIMER_OOL_WORKAROUND	help	  This option enables a workaround for Freescale/NXP Erratum	  A-008585 ("ARM generic timer may contain an erroneous	  value").

Should its parent clock	  change, the driver tries to fix the timer's internal prescaler.	  On some machs (i.e. Zynq) the initial prescaler value thus poses	  bounds about how much the parent clock is allowed to decrease or	  increase wrt the initial clock value.	  This affects CPU_FREQ max delta from the initial frequency.
