6 tristate "Industrial I/O support"
7 depends on GENERIC_HARDIRQS
9 The industrial I/O subsystem provides a unified framework for
10 drivers for many different types of embedded sensors using a
11 number of different physical interfaces (i2c, spi, etc). See
12 drivers/staging/iio/Documentation for more information.
16 bool "Enable buffer support within IIO"
18 Provide core support for various buffer based data
25 tristate "Industrial I/O lock free software ring"
27 Example software ring buffer implementation. The design aim
28 of this particular realization was to minimize write locking
29 with the intention that some devices would be able to write
34 tristate "Industrial I/O buffering based on kfifo"
36 A simple fifo based on kfifo. Use this if you want a fifo
37 rather than a ring buffer. Note that this currently provides
38 no buffer events so it is up to userspace to work out how
39 often to read from the buffer.
44 boolean "Enable triggered sampling support"
46 Provides IIO core support for triggers. Currently these
47 are used to initialize capture of samples to push into
48 ring buffers. The triggers are effectively a 'capture
51 config IIO_CONSUMERS_PER_TRIGGER
52 int "Maximum number of consumers per trigger"
53 depends on IIO_TRIGGER
56 This value controls the maximum number of consumers that a
57 given trigger may handle. Default is 2.

82 a driver. May also be useful for testing userspace code
