|  | 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. |

|  | 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. |

|  | 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. |
