  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).

 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.
