config ARM_ARCH_TIMER_EVTSTREAM
	bool "Support for ARM architected timer event stream generation"
	default y if ARM_ARCH_TIMER
	help
	  This option enables support for event stream generation based on
	  the ARM architected timer. It is used for waking up CPUs executing
	  the wfe instruction at a frequency represented as a power-of-2
	  divisor of the clock rate.
	  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 CLKSRC_SAMSUNG_PWM
	bool
	help
	  This is a new clocksource driver for the PWM timer found in
	  Samsung S3C, S5P and Exynos SoCs, replacing an earlier driver
	  for all devicetree enabled platforms. This driver will be
	  needed only on systems that do not have the Exynos MCT available.

config VF_PIT_TIMER
	bool
	help
	  Support for Period Interrupt Timer on Freescale Vybrid Family SoCs.
