The AD74412R and AD74413R are quad-channel, software configurable, input/output solutions for building and process control applications. They contain functionality for analog output, analog input, digital input, resistance temperature detector, and thermocouple measurements integrated into a single chip solution with an SPI interface. The devices feature a 16-bit ADC and four configurable 13-bit DACs to provide four configurable input/output channels and a suite of diagnostic functions. The AD74413R differentiates itself from the AD74412R by being HART-compatible. When configured with channel 0 as voltage output, channel 1 as current output, channel 2 as voltage input and channel 3 as current input, the following structure is created under the corresponding IIO device. . ├── in_current0_offset ├── in_current0_raw ├── in_current0_sampling_frequency ├── in_current0_sampling_frequency_available ├── in_current0_scale ├── in_voltage1_offset ├── in_voltage1_raw ├── in_voltage1_sampling_frequency ├── in_voltage1_sampling_frequency_available ├── in_voltage1_scale ├── in_voltage2_offset ├── in_voltage2_raw ├── in_voltage2_sampling_frequency ├── in_voltage2_sampling_frequency_available ├── in_voltage2_scale ├── in_current3_offset ├── in_current3_raw ├── in_current3_sampling_frequency ├── in_current3_sampling_frequency_available ├── in_current3_scale ├── out_voltage0_raw ├── out_voltage0_scale ├── out_current1_raw ├── out_current1_scale ├── name ├── buffer │ ├── data_available │ ├── enable │ ├── length │ └── watermark └── scan_elements ├── in_current0_en ├── in_current0_index ├── in_current0_type ├── in_voltage1_en ├── in_voltage1_index ├── in_voltage1_type ├── in_voltage2_en ├── in_voltage2_index ├── in_voltage2_type ├── in_current3_en ├── in_current3_index └── in_current3_type Signed-off-by: Cosmin Tanislav <cosmin.tanislav@analog.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Link: https://lore.kernel.org/r/20211205114045.173612-4-cosmin.tanislav@analog.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Say yes here to build support for Analog Devices AD74412R/AD74413R
|
|
quad-channel software configurable input/output solution.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called ad74413r.
