+config IIO_HRTIMER_TRIGGER
+	tristate "High resolution timer trigger"
+	depends on IIO_SW_TRIGGER
+	help
+	  Provides a frequency based IIO trigger using high resolution
+	  timers as interrupt source.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called iio-trig-hrtimer.
+
+config IIO_INTERRUPT_TRIGGER
+	tristate "Generic interrupt trigger"
+	help
+	  Provides support for using an interrupt of any type as an IIO
+	  trigger.  This may be provided by a gpio driver for example.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called iio-trig-interrupt.
+
+config IIO_STM32_LPTIMER_TRIGGER
+	tristate "STM32 Low-Power Timer Trigger"
+	depends on MFD_STM32_LPTIMER || COMPILE_TEST
+	help
+	  Select this option to enable STM32 Low-Power Timer Trigger.
+	  This can be used as trigger source for STM32 internal ADC
+	  and/or DAC.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called stm32-lptimer-trigger.
+
+config IIO_STM32_TIMER_TRIGGER
+	tristate "STM32 Timer Trigger"
+	depends on (ARCH_STM32 && OF && MFD_STM32_TIMERS) || COMPILE_TEST
+	help
+	  Select this option to enable STM32 Timer Trigger
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called stm32-timer-trigger.
+
+config IIO_TIGHTLOOP_TRIGGER
+	tristate "A kthread based hammering loop trigger"
+	depends on IIO_SW_TRIGGER
+	help
+	  An experimental trigger, used to allow sensors to be sampled as fast
+	  as possible under the limitations of whatever else is going on.
+	  Uses a tight loop in a kthread.  Will only work with lower half only
+	  trigger consumers.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called iio-trig-loop.
+
+config IIO_SYSFS_TRIGGER
+	tristate "SYSFS trigger"
+	depends on SYSFS
+	select IRQ_WORK
+	help
+	  Provides support for using SYSFS entries as IIO triggers.
+	  If unsure, say N (but it's safe to say "Y").
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called iio-trig-sysfs.
