# # Industrial I/O subsystem configuration # menuconfig IIO tristate "Industrial I/O support" select ANON_INODES 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). 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_BUFFER_CB bool "IIO callback buffer used for push in-kernel interfaces" help Should be selected by any drivers that do in-kernel push usage. That is, those where the data is pushed to the consumer. config IIO_KFIFO_BUF tristate "Industrial I/O buffering based on kfifo" help A simple fifo based on kfifo. Note that this currently provides no buffer events so it is up to userspace to work out how often to read from the buffer. config IIO_TRIGGERED_BUFFER tristate select IIO_TRIGGER select IIO_KFIFO_BUF help Provides helper functions for setting up triggered buffers. endif # IIO_BUFFER config IIO_TRIGGER bool "Enable triggered sampling support" help Provides IIO core support for triggers. Currently these are used to initialize capture of samples to push into 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. source "drivers/iio/accel/Kconfig" source "drivers/iio/adc/Kconfig" source "drivers/iio/amplifiers/Kconfig" source "drivers/iio/common/Kconfig" source "drivers/iio/dac/Kconfig" source "drivers/iio/frequency/Kconfig" source "drivers/iio/gyro/Kconfig" source "drivers/iio/humidity/Kconfig" source "drivers/iio/imu/Kconfig" source "drivers/iio/light/Kconfig" source "drivers/iio/magnetometer/Kconfig" source "drivers/iio/orientation/Kconfig" if IIO_TRIGGER source "drivers/iio/trigger/Kconfig" endif #IIO_TRIGGER source "drivers/iio/pressure/Kconfig" source "drivers/iio/proximity/Kconfig" source "drivers/iio/temperature/Kconfig" endif # IIO
