   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           usage.  That is, those where the data is pushed to the consumer.

  33           A simple fifo based on kfifo.  Note that this currently provides
  34           no buffer events so it is up to userspace to work out how
  35           often to read from the buffer.

  49           Provides IIO core support for triggers.  Currently these
  50           are used to initialize capture of samples to push into
  51           buffers.  The triggers are effectively a 'capture

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