+menuconfig IIO
+	tristate "Industrial I/O support"
+	select ANON_INODES
+	help
+	  The industrial I/O subsystem provides a unified framework for
+	  drivers for many different types of embedded sensors using a
+	  number of different physical interfaces (i2c, spi, etc).
+
+if IIO
+
+config IIO_BUFFER
+	bool "Enable buffer support within IIO"
+	help
+	  Provide core support for various buffer based data
+	  acquisition methods.
+
+if IIO_BUFFER
+
+config IIO_BUFFER_CB
+	bool "IIO callback buffer used for push in-kernel interfaces"
+	help
+	  Should be selected by any drivers that do in-kernel push
+	  usage.  That is, those where the data is pushed to the consumer.
+
+config IIO_KFIFO_BUF
+	tristate "Industrial I/O buffering based on kfifo"
+	help
+	  A simple fifo based on kfifo.  Note that this currently provides
+	  no buffer events so it is up to userspace to work out how
+	  often to read from the buffer.
+
+config IIO_TRIGGERED_BUFFER
+	tristate
+	select IIO_TRIGGER
+	select IIO_KFIFO_BUF
+	help
+	  Provides helper functions for setting up triggered buffers.
+
+endif # IIO_BUFFER
+
+config IIO_TRIGGER
+	bool "Enable triggered sampling support"
+	help
+	  Provides IIO core support for triggers.  Currently these
+	  are used to initialize capture of samples to push into
+	  buffers.  The triggers are effectively a 'capture
+	  data now' interrupt.
+
+config IIO_CONSUMERS_PER_TRIGGER
+       int "Maximum number of consumers per trigger"
+       depends on IIO_TRIGGER
+       default "2"
+       help
+	This value controls the maximum number of consumers that a
+	given trigger may handle. Default is 2.
