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). |

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. | |

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

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