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). See
12	  Documentation/iio for more information.

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

36	boolean "Enable triggered sampling support"
37	help
38	  Provides IIO core support for triggers.  Currently these
39	  are used to initialize capture of samples to push into
40	  ring buffers.  The triggers are effectively a 'capture
41	  data now' interrupt.

48	This value controls the maximum number of consumers that a
