2 # Industrial I/O subsystem configuration
6 tristate "Industrial I/O support"
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).
15 bool "Enable buffer support within IIO"
17 Provide core support for various buffer based data
23 boolean "IIO callback buffer used for push in-kernel interfaces"
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.
30 tristate "Industrial I/O buffering based on kfifo"
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
41 Provides helper functions for setting up triggered buffers.
46 boolean "Enable triggered sampling support"
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
53 config IIO_CONSUMERS_PER_TRIGGER
54 int "Maximum number of consumers per trigger"
55 depends on IIO_TRIGGER
58 This value controls the maximum number of consumers that a
59 given trigger may handle. Default is 2.
