   8           The industrial I/O subsystem provides a unified framework for
   9           drivers for many different types of embedded sensors using a
  10           number of different physical interfaces (i2c, spi, etc).

  25           Should be selected by any drivers that do in-kernel push
  26           usage.  That is, those where the data is pushed to the consumer.

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

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

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