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).

18	  Provide core support for various buffer based data
19	  acquisition methods.

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

31	tristate "Industrial I/O buffering based on kfifo"
32	help
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.

37config IIO_TRIGGERED_BUFFER
38	tristate
39	select IIO_TRIGGER

42	  Provides helper functions for setting up triggered buffers.

46config IIO_TRIGGER
47	boolean "Enable triggered sampling support"
48	help
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
52	  data now' interrupt.

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