[ Upstream commit1a97905d3e] This is a Framework to handle complex IIO aggregate devices. The typical architecture is to have one device as the frontend device which can be "linked" against one or multiple backend devices. All the IIO and userspace interface is expected to be registers/managed by the frontend device which will callback into the backends when needed (to get/set some configuration that it does not directly control). The basic framework interface is pretty simple: - Backends should register themselves with @devm_iio_backend_register() - Frontend devices should get backends with @devm_iio_backend_get() Signed-off-by: Nuno Sa <nuno.sa@analog.com> Link: https://lore.kernel.org/r/20240210-iio-backend-v11-5-f5242a5fb42a@analog.com Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Stable-dep-of:cf1c833f89("iio: adc: adi-axi-adc: only error out in major version mismatch") Signed-off-by: Sasha Levin <sashal@kernel.org>

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_GTS_HELPER tristate
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.
config IIO_BACKEND tristate help Framework to handle complex IIO aggregate devices. The typical architecture that can make use of this framework is to have one device as the frontend device which can be "linked" against one or multiple backend devices. The framework then makes it easy to get and control such backend devices.
