2024-08-10iio: adc: stm32-dfsdm: add scaling support to dfsdmOlivier Moysan
Add scaling support to STM32 DFSDM. When used in an analog context, a DFSDM filter typically converts the data from a sigma delta modulator. The IIO device associated to the DFSDM filter provides these data as raw data. The IIO device can provide scaling information (voltage and offset) to allow conversion of raw data into physical values. With the new binding based on IIO backend framework, the sigma delta modulators are defined as backends providing scaling information. The scaling is not supported with legacy binding.

2024-08-10iio: add iio backend support to sd modulatorOlivier Moysan
The legacy sd modulator driver registers the sigma delta modulator as an IIO channel provider. This implementation is not convenient when the SD modulator has to be cascaded with another IIO device. The scaling information is distributed across devices, which makes it difficult to report consistent scaling data on IIO devices. The solution is to expose these cascaded IIO devices as an aggregate device, which report global scaling information. Add IIO backend support to SD modulator to allow scaling information management.

Convert the driver to use the new IIO backend framework. The device functionality is expected to be the same (meaning no added or removed features). Also note this patch effectively breaks ABI and that's needed so we can properly support this device and add needed features making use of the new IIO framework. Given the lack of features (and devices supported) in the ad9467 driver compared with the ADI out of tree version, we don't expect any user of the upstream driver so no one should notice the ABI breakage. However, if someone is affected by this, ADI will happily support transitioning to the backend framework.

2023-11-16iio: adc: Add driver support for MAX34408/9Ivan Mikhaylov
The MAX34408/MAX34409 are two- and four-channel current monitors that are configured and monitored with a standard I2C/SMBus serial interface. Each unidirectional current sensor offers precision high-side operation with a low full-scale sense voltage. The devices automatically sequence through two or four channels and collect the current-sense samples and average them to reduce the effect of impulse noise. The raw ADC samples are compared to user-programmable digital thresholds to indicate overcurrent conditions. Overcurrent conditions trigger a hardware output to provide an immediate indication to shut down any necessary external circuitry. Add as ADC driver which only supports current monitoring for now.

2022-12-28iio: adc: add ADC driver for the TI LMP92064 controllerLeonard Göhrs
The TI LMP92064 is a dual 12 Bit ADC connected via SPI. The two channels are intended for simultaneous measurements of the voltage across- and current through a load to allow accurate instantaneous power measurements. The driver does not yet take advantage of this feature, as buffering is not yet implemented.

Adding support for max11410 24-bit, 1.9ksps delta-sigma adc which has 3 differential reference and 10 differential channel inputs. Inputs and references can be buffered internally. Inputs can also be amplified with internal PGA. Device has four digital filter modes: FIR50/60, FIR50, FIR60 and SINC4. FIR 50Hz and 60Hz rejections can be enabled/disabled separately. Digital filter selection affects sampling frequency range so driver has to consider the configured filter when configuring sampling frequency.
