  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.  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.
