8	help
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).

19	  acquisition methods.

26	help
27	  A simple fifo based on kfifo.  Use this if you want a fifo
28	  rather than a ring buffer. Note that this currently provides
29	  no buffer events so it is up to userspace to work out how
30	  often to read from the buffer.

42	boolean "Enable triggered sampling support"
43	help
44	  Provides IIO core support for triggers.  Currently these
45	  are used to initialize capture of samples to push into
46	  ring buffers.  The triggers are effectively a 'capture
47	  data now' interrupt.

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