The Documentation/devicetree/bindings/gpio/gpio-consumer-common.yaml
schema does not enforce number of reset GPIOs, thus each device binding
must do it.

dtschema v2023.06 comes with support for properties with -nanoamp
suffix, thus bindings should not have a ref for it:
adi,ad74115.yaml: properties:adi,ext1-burnout-current-nanoamp: '$ref' should not be valid under {'const': '$ref'}

Depending on the actual hardware wired up to a digital input channel,
it may be necessary to configure the ad74413r to sink a small
current. For example, in the case of a simple mechanical switch, the
charge on the external 68 nF capacitor (cf. the data sheet's Figure
34) will keep the channel as reading high even after the switch is
turned off again.

The ad74412 and ad74413 devices have an active-low reset pin. Add a
binding allowing one to specify a gpio tied to that.

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.

Improve example by: dropping unrelated properties (status and cs-gpios)
and using generic node name.

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.

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

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.
