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 | Should be selected by any drivers that do-inkernel push | |

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. | |

49 | help | |
50 | Provides IIO core support for triggers. Currently these | |
51 | are used to initialize capture of samples to push into | |
52 | ring buffers. The triggers are effectively a 'capture | |
53 | data now' interrupt. | |

60 | This value controls the maximum number of consumers that a | |
