   7         tristate "IIO callback buffer used for push in-kernel interfaces"
   8         help
   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.

  12 config IIO_BUFFER_DMA
  13         tristate
  14         help
  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.
  17
  18           Should be selected by drivers that want to use the generic DMA buffer
  19           infrastructure.

  21 config IIO_BUFFER_DMAENGINE
  22         tristate
  23         select IIO_BUFFER_DMA
  24         help
  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
  28           DMAengine framework.
  29
  30           Should be selected by drivers that want to use this functionality.

  32 config IIO_KFIFO_BUF
  33         tristate "Industrial I/O buffering based on kfifo"
  34         help
  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
  40         tristate
  41         select IIO_TRIGGER
  42         select IIO_KFIFO_BUF
  43         help
  44           Provides helper functions for setting up triggered buffers.
