10	  drivers for many different types of embedded sensors using a
11	  number of different physical interfaces (i2c, spi, etc).

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