   6config IIO_BUFFER_CB
   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.
  11
  12config 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.

  21config 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.
  31
  32config 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.
  38
  39config 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.
