   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).

  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.

  51           are used to initialize capture of samples to push into
  52           ring buffers.  The triggers are effectively a 'capture
