+config IIO_BUFFER_CB
+ tristate "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_BUFFER_DMA
+ tristate
+ help
+ Provides the generic IIO DMA buffer infrastructure that can be used by
+ drivers for devices with DMA support to implement the IIO buffer.
+
+ Should be selected by drivers that want to use the generic DMA buffer
+ infrastructure.
+
+config IIO_BUFFER_DMAENGINE
+ tristate
+ select IIO_BUFFER_DMA
+ help
+ Provides a bonding of the generic IIO DMA buffer infrastructure with the
+ DMAengine framework. This can be used by converter drivers with a DMA port
+ connected to an external DMA controller which is supported by the
+ DMAengine framework.
+
+ Should be selected by drivers that want to use this functionality.
+
+config IIO_BUFFER_HW_CONSUMER
+ tristate "Industrial I/O HW buffering"
+ help
+ Provides a way to bonding when an IIO device has a direct connection
+ to another device in hardware. In this case buffers for data transfers
+ are handled by hardware.
+
+ Should be selected by drivers that want to use the generic Hw consumer
+ interface.
+
+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.
