- tristate "Industrial I/O support"
- depends on GENERIC_HARDIRQS
- help
- The industrial I/O subsystem provides a unified framework for
- drivers for many different types of embedded sensors using a
- number of different physical interfaces (i2c, spi, etc). See
- Documentation/iio for more information.
- if IIO
- config IIO_BUFFER
- bool "Enable buffer support within IIO"
- help
- Provide core support for various buffer based data
- acquisition methods.
- if IIO_BUFFER
- config IIO_KFIFO_BUF
- select IIO_TRIGGER
- tristate "Industrial I/O buffering based on kfifo"
- help
- A simple fifo based on kfifo. Use this if you want a fifo
- rather than a ring buffer. Note that this currently provides
- no buffer events so it is up to userspace to work out how
- often to read from the buffer.
- endif # IIO_BUFFER
- config IIO_TRIGGER
- boolean "Enable triggered sampling support"
- help
- Provides IIO core support for triggers. Currently these
- are used to initialize capture of samples to push into
- ring buffers. The triggers are effectively a 'capture
- data now' interrupt.
- config IIO_CONSUMERS_PER_TRIGGER
- int "Maximum number of consumers per trigger"
- depends on IIO_TRIGGER
- default "2"
- help
- This value controls the maximum number of consumers that a
- given trigger may handle. Default is 2.
