| 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. |

| 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. |

| 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. |

| 33 | tristate "Industrial I/O HW buffering" |
| 34 | help |
| 35 | Provides a way to bonding when an IIO device has a direct connection |
| 36 | to another device in hardware. In this case buffers for data transfers |
| 37 | are handled by hardware. |
| 38 | |
| 39 | Should be selected by drivers that want to use the generic Hw consumer |
| 40 | interface. |

| 43 | tristate "Industrial I/O buffering based on kfifo" |
| 44 | help |
| 45 | A simple fifo based on kfifo. Note that this currently provides |
| 46 | no buffer events so it is up to userspace to work out how |
| 47 | often to read from the buffer. |
