+menuconfig IIO
+ tristate "Industrial I/O support"
+ depends on GENERIC_HARDIRQS
+ 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). See
+ Documentation/iio for more information.

+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_KFIFO_BUF
+ select IIO_TRIGGER
+ tristate "Industrial I/O buffering based on kfifo"
+ help
+ A simple fifo based on kfifo. Use this if you want a fifo
+ rather than a ring buffer. 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_TRIGGER
+ boolean "Enable triggered sampling support"
+ help
+ Provides IIO core support for triggers. Currently these
+ are used to initialize capture of samples to push into
+ ring 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.
