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 ARM_GLOBAL_TIMER	bool	select CLKSRC_OF if OF	help	  This options enables support for the ARM global timer unit config ARM_TIMER_SP804	bool "Support for Dual Timer SP804 module"	depends on GENERIC_SCHED_CLOCK && CLKDEV_LOOKUP	select CLKSRC_MMIO	select CLKSRC_OF if OF config CLKSRC_ARM_GLOBAL_TIMER_SCHED_CLOCK	bool	depends on ARM_GLOBAL_TIMER	default y	help	 Use ARM global timer clock source as sched_clock config ARMV7M_SYSTICK	bool	select CLKSRC_OF if OF	select CLKSRC_MMIO	help	  This options enables support for the ARMv7M system timer unit config ATMEL_PIT	select CLKSRC_OF if OF	def_bool SOC_AT91SAM9 || SOC_SAMA5 config ATMEL_ST	bool	select CLKSRC_OF	select MFD_SYSCON config CLKSRC_METAG_GENERIC	def_bool y if METAG	help	  This option enables support for the Meta per-thread timers. config CLKSRC_EXYNOS_MCT	def_bool y if ARCH_EXYNOS	depends on !ARM64	help	  Support for Multi Core Timer controller on Exynos SoCs. 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.
