| 8 | config IIO_HRTIMER_TRIGGER |
| 9 | tristate "High resolution timer trigger" |
| 10 | depends on IIO_SW_TRIGGER |
| 11 | help |
| 12 | Provides a frequency based IIO trigger using high resolution |
| 13 | timers as interrupt source. |
| 14 | |
| 15 | To compile this driver as a module, choose M here: the |
| 16 | module will be called iio-trig-hrtimer. |
| 17 | |
| 18 | config IIO_INTERRUPT_TRIGGER |
| 19 | tristate "Generic interrupt trigger" |
| 20 | help |
| 21 | Provides support for using an interrupt of any type as an IIO |
| 22 | trigger. This may be provided by a gpio driver for example. |
| 23 | |
| 24 | To compile this driver as a module, choose M here: the |
| 25 | module will be called iio-trig-interrupt. |

| 27 | config IIO_STM32_LPTIMER_TRIGGER |
| 28 | tristate "STM32 Low-Power Timer Trigger" |
| 29 | depends on MFD_STM32_LPTIMER || COMPILE_TEST |
| 30 | help |
| 31 | Select this option to enable STM32 Low-Power Timer Trigger. |
| 32 | This can be used as trigger source for STM32 internal ADC |
| 33 | and/or DAC. |
| 34 | |
| 35 | To compile this driver as a module, choose M here: the |
| 36 | module will be called stm32-lptimer-trigger. |

| 38 | config IIO_STM32_TIMER_TRIGGER |
| 39 | tristate "STM32 Timer Trigger" |
| 40 | depends on (ARCH_STM32 && OF && MFD_STM32_TIMERS) || COMPILE_TEST |
| 41 | help |
| 42 | Select this option to enable STM32 Timer Trigger |
| 43 | |
| 44 | To compile this driver as a module, choose M here: the |
| 45 | module will be called stm32-timer-trigger. |

| 47 | config IIO_TIGHTLOOP_TRIGGER |
| 48 | tristate "A kthread based hammering loop trigger" |
| 49 | depends on IIO_SW_TRIGGER |
| 50 | help |
| 51 | An experimental trigger, used to allow sensors to be sampled as fast |
| 52 | as possible under the limitations of whatever else is going on. |
| 53 | Uses a tight loop in a kthread. Will only work with lower half only |
| 54 | trigger consumers. |
| 55 | |
| 56 | To compile this driver as a module, choose M here: the |
| 57 | module will be called iio-trig-loop. |

| 59 | config IIO_SYSFS_TRIGGER |
| 60 | tristate "SYSFS trigger" |
| 61 | depends on SYSFS |
| 62 | select IRQ_WORK |
| 63 | help |
| 64 | Provides support for using SYSFS entries as IIO triggers. |
| 65 | If unsure, say N (but it's safe to say "Y"). |
| 66 | |
| 67 | To compile this driver as a module, choose M here: the |
| 68 | module will be called iio-trig-sysfs. |
