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).

28	help
29	  This allows configuring various IIO bits through configfs
30	  (e.g. software triggers). For more info see
31	  Documentation/iio/iio_configfs.rst.

33config IIO_TRIGGER
34	bool "Enable triggered sampling support"
35	help
36	  Provides IIO core support for triggers.  Currently these
37	  are used to initialize capture of samples to push into
38	  buffers.  The triggers are effectively a 'capture
39	  data now' interrupt.

44	default "2"
45	help
46	  This value controls the maximum number of consumers that a
47	  given trigger may handle. Default is 2.

51	select IIO_CONFIGFS
52	help
53	  Provides IIO core support for software devices. A software
54	  device can be created via configfs or directly by a driver
55	  using the API provided.
