dt-bindings: iio: ad74413r: add optional reset-gpios

2022-11-23T20:54:37Z

The ad74412 and ad74413 devices have an active-low reset pin. Add a binding allowing one to specify a gpio tied to that. Signed-off-by: Rasmus Villemoes Acked-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20221115095517.1008632-3-linux@rasmusvillemoes.dk Signed-off-by: Jonathan Cameron

dt-bindings: iio: addac: add AD74115

2022-11-23T20:49:00Z

The AD74115H is a single-channel, software-configurable, input and output device for industrial control applications. The AD74115H provides a wide range of use cases, integrated on a single chip. These use cases include analog output, analog input, digital output, digital input, resistance temperature detector (RTD), and thermocouple measurement capability. The AD74115H also has an integrated HART modem. A serial peripheral interface (SPI) is used to handle all communications to the device, including communications with the HART modem. The digital input and digital outputs can be accessed via the SPI or the general-purpose input and output (GPIO) pins to support higher speed data rates. The device features a 16-bit, sigma-delta analog-to-digital converter (ADC) and a 14-bit digital-to-analog converter (DAC). The AD74115H contains a high accuracy 2.5 V on-chip reference that can be used as the DAC and ADC reference.

dt-bindings: iio: addac: adi,ad74413r: improve example

2022-11-23T19:43:58Z

Improve example by: dropping unrelated properties (status and cs-gpios) and using generic node name. Signed-off-by: Krzysztof Kozlowski Acked-by: Rob Herring Link: https://lore.kernel.org/r/20221004115642.63749-2-krzysztof.kozlowski@linaro.org Signed-off-by: Jonathan Cameron

dt-bindings: iio: addac: adi,ad74413r: use spi-peripheral-props.yaml

2022-11-23T19:43:58Z

Reference the spi-peripheral-props.yaml schema to allow using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS.

dt-bindings: iio: Add missing (unevaluated|additional)Properties on child nodes

2022-08-30T17:35:38Z

In order to ensure only documented properties are present, node schemas must have unevaluatedProperties or additionalProperties set to false (typically).

dt-bindings: iio: add AD74413R

2021-12-12T17:09:11Z

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.
