7         help
8           The industrial I/O subsystem provides a unified framework for
9           drivers for many different types of embedded sensors using a
10           number of different physical interfaces (i2c, spi, etc).

14 config IIO_BUFFER
15         bool "Enable buffer support within IIO"
16         help
17           Provide core support for various buffer based data
18           acquisition methods.

23 boolean "IIO callback buffer used for push in-kernel interfaces"
24         help
25           Should be selected by any drivers that do in-kernel push
26           usage.  That is, those where the data is pushed to the consumer.

31         help
32           A simple fifo based on kfifo.  Note that this currently provides
33           no buffer events so it is up to userspace to work out how
34           often to read from the buffer.
36 config IIO_TRIGGERED_BUFFER
37         tristate

41           Provides helper functions for setting up triggered buffers.

45 config IIO_TRIGGER
46         boolean "Enable triggered sampling support"
47         help
48           Provides IIO core support for triggers.  Currently these
49           are used to initialize capture of samples to push into
50           buffers.  The triggers are effectively a 'capture
51           data now' interrupt.

58         This value controls the maximum number of consumers that a
59         given trigger may handle. Default is 2.
