| 9 | The industrial I/O subsystem provides a unified framework for |
| 10 | drivers for many different types of embedded sensors using a |
| 11 | number of different physical interfaces (i2c, spi, etc). |

| 26 | help |
| 27 | A simple fifo based on kfifo. Use this if you want a fifo |
| 28 | rather than a ring buffer. Note that this currently provides |
| 29 | no buffer events so it is up to userspace to work out how |
| 30 | often to read from the buffer. |

| 44 | Provides IIO core support for triggers. Currently these |
| 45 | are used to initialize capture of samples to push into |
| 46 | ring buffers. The triggers are effectively a 'capture |
