   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).

  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
  47           data now' interrupt.

  54         This value controls the maximum number of consumers that a
  55         given trigger may handle. Default is 2.
