+menuconfig IIO
+ tristate "Industrial I/O support"
+ 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).

+config IIO_BUFFER
+ bool "Enable buffer support within IIO"
+ help
+ Provide core support for various buffer based data
+ acquisition methods.
+
+if IIO_BUFFER
+ source "drivers/iio/buffer/Kconfig"
+endif # IIO_BUFFER
+
+config IIO_CONFIGFS
+ tristate "Enable IIO configuration via configfs"
+ select CONFIGFS_FS
+ help
+ This allows configuring various IIO bits through configfs
+ (e.g. software triggers). For more info see
+ Documentation/iio/iio_configfs.rst.
+
+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.
+
+config IIO_SW_DEVICE
+ tristate "Enable software IIO device support"
+ select IIO_CONFIGFS
+ help
+ Provides IIO core support for software devices. A software
+ device can be created via configfs or directly by a driver
+ using the API provided.
+
+config IIO_SW_TRIGGER
+ tristate "Enable software triggers support"
+ select IIO_CONFIGFS
+ help
+ Provides IIO core support for software triggers. A software
+ trigger can be created via configfs or directly by a driver
+ using the API provided.
+
+config IIO_TRIGGERED_EVENT
+ tristate "Enable triggered events support"
+ select IIO_TRIGGER
+ help
+ Provides helper functions for setting up triggered events.
