config EXAMPLES_TIMER_GPOUT
	tristate "Timer GPOUT example"
	default n
	depends on TIMER && DEV_GPIO
	---help---
		Enable the timer-gpout example.
		This example uses the timer interrupt to periodically
		change the state of a digital output.
		The digital output may be a relay, a led or anything else.
		This example can be very useful to validate timer drivers
		by using a logic analyzer connected to the digital output.
		This example, differs from the timer example because it
		waits on a sigwaitinfo() instead of using a signal handler.
		This approach ensures a deterministic wake-up time when
		the signal occurs.
