| 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). See |
| 12 | Documentation/iio for more information. |

| 27 | help |
| 28 | A simple fifo based on kfifo. Use this if you want a fifo |
| 29 | rather than a ring buffer. Note that this currently provides |
| 30 | no buffer events so it is up to userspace to work out how |
| 31 | often to read from the buffer. |

| 37 | help |
| 38 | Provides IIO core support for triggers. Currently these |
| 39 | are used to initialize capture of samples to push into |
| 40 | ring buffers. The triggers are effectively a 'capture |
| 41 | data now' interrupt. |

| 48 | This value controls the maximum number of consumers that a |
| 49 | given trigger may handle. Default is 2. |
