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_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
	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.
