menuconfig IIO
tristate "Industrial I/O support"
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
source "drivers/iio/buffer/Kconfig"
endif # IIO_BUFFER
config IIO_CONFIGFS
tristate "Enable IIO configuration via configfs"
select CONFIGFS_FS
help
This allows configuring various IIO bits through configfs
(e.g. software triggers). For more info see
Documentation/iio/iio_configfs.rst.
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.
config IIO_SW_DEVICE
tristate "Enable software IIO device support"
select IIO_CONFIGFS
help
Provides IIO core support for software devices. A software
device can be created via configfs or directly by a driver
using the API provided.
config IIO_SW_TRIGGER
tristate "Enable software triggers support"
select IIO_CONFIGFS
help
Provides IIO core support for software triggers. A software
trigger can be created via configfs or directly by a driver
using the API provided.
config IIO_TRIGGERED_EVENT
tristate "Enable triggered events support"
select IIO_TRIGGER
help
Provides helper functions for setting up triggered events.
