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 Documentation/iio for more information.

27 help
28 A simple fifo based on kfifo. Use this if you want a fifo
29 rather than a ring buffer. Note that this currently provides
30 no buffer events so it is up to userspace to work out how
31 often to read from the buffer.

36 boolean "Enable triggered sampling support"
37 help
38 Provides IIO core support for triggers. Currently these
39 are used to initialize capture of samples to push into
40 ring buffers. The triggers are effectively a 'capture
41 data now' interrupt.

43config IIO_CONSUMERS_PER_TRIGGER

46 default "2"
47 help
48 This value controls the maximum number of consumers that a
49 given trigger may handle. Default is 2.
