| 9 | The industrial I/O subsystem provides a unified framework for | |
| 10 | drivers for many different types of embedded sensors using a | |
| a529ae4b | 11 | number of different physical interfaces (i2c, spi, etc). |

| 32 | help | |
| 33 | A simple fifo based on kfifo. Use this if you want a fifo | |
| 34 | rather than a ring buffer. Note that this currently provides | |
| 35 | no buffer events so it is up to userspace to work out how | |
| 36 | often to read from the buffer. | |

| 50 | Provides IIO core support for triggers. Currently these | |
| 51 | are used to initialize capture of samples to push into | |
