config EXAMPLES_WATCHDOG
	tristate "Watchdog Timer example"
	default n
	---help---
		Enable the watchdog timer example

		In order to use this example, board specific logic must register the
		watchdog timer driver.  That would be in the board bring-up logic
		in the configs/<board>/src directory for the board.

		The way that this is done depends on the underlying MCU architecture.
		For STM32, this would be done like:

			#include "stm32_wdg.h"

			#if defined(CONFIG_STM32_WWDG)
			  stm32_wwdginitialize(CONFIG_STM32_WDG_DEVPATH);
			#elif defined(CONFIG_STM32_IWDG)
			  stm32_iwdginitialize(CONFIG_STM32_WDG_DEVPATH, CONFIG_STM32_LSIFREQ);
			#endif

		For some Atmel SAM configurations, the board-specific initialization
		sequence would be like:

			#include "sam_wdt.h"

			sam_wdt_initialize();

config EXAMPLES_WATCHDOG_DEVPATH
	string "Watchdog device path"
	default "/dev/watchdog0"
	---help---
		The path to the watchdog device. Default: /dev/watchdog0

config EXAMPLES_WATCHDOG_PINGTIME
	int "Watchdog ping time"
	default 5000
	---help---
		Time in milliseconds that the example will ping the watchdog before letting the
		watchdog expire. Default: 5000 milliseconds.

config EXAMPLES_WATCHDOG_PINGDELAY
	int "Watchdog ping delay"
	default 500
	---help---
		Time delay between pings in milliseconds. Default: 500 milliseconds.

config EXAMPLES_WATCHDOG_TIMEOUT
	int "Watchdog timeout"
	default 2000
	---help---
		The watchdog timeout value in milliseconds before the watchdog timer
		expires.  Default:  2000 milliseconds.
