7 tristate "IIO callback buffer used for push in-kernel interfaces"
9 Should be selected by any drivers that do in-kernel push
10 usage. That is, those where the data is pushed to the consumer.
15 Provides the generic IIO DMA buffer infrastructure that can be used by
16 drivers for devices with DMA support to implement the IIO buffer.
18 Should be selected by drivers that want to use the generic DMA buffer
21 config IIO_BUFFER_DMAENGINE
25 Provides a bonding of the generic IIO DMA buffer infrastructure with the
26 DMAengine framework. This can be used by converter drivers with a DMA port
27 connected to an external DMA controller which is supported by the
30 Should be selected by drivers that want to use this functionality.
33 tristate "Industrial I/O buffering based on kfifo"
35 A simple fifo based on kfifo. Note that this currently provides
36 no buffer events so it is up to userspace to work out how
37 often to read from the buffer.
39 config IIO_TRIGGERED_BUFFER
44 Provides helper functions for setting up triggered buffers.
