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 "Industrial I/O DMA buffer infrastructure"
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 "Industrial I/O DMA buffer integration with DMAEngine"
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 "Industrial I/O triggered buffer support"
select IIO_TRIGGER
select IIO_KFIFO_BUF
help
Provides helper functions for setting up triggered buffers.
