| 12 | help |
| 13 | Provides a frequency based IIO trigger using high resolution |
| 14 | timers as interrupt source. |

| 24 | This can be used as trigger source for STM32 internal ADC |
| 25 | and/or DAC. |

| 42 | help |
| 43 | An experimental trigger, used to allow sensors to be sampled as fast |
| 44 | as possible under the limitations of whatever else is going on. |
| 45 | Uses a tight loop in a kthread. Will only work with lower half only |
| 46 | trigger consumers. |

| 56 | Provides support for using SYSFS entries as IIO triggers. |
| 57 | If unsure, say N (but it's safe to say "Y"). |
