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).

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
	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.txt.

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
	select IIO_TRIGGER
	help
	  Provides helper functions for setting up triggered events.
