thanks all for your input.
I conclude here in one answer:

sorry i missed that, fixed for [Patch v2].

replaced with
renesas,shunt-range-milli-volts:
description: |
maximal shunt voltage range of 40mV, 80mV, 160mV or 320mV
$ref: /schemas/types.yaml#/definitions/uint32-array
default: 320
enum: [40, 80, 160, 320]

When shunt resistor value is not known, current and power calculation can not be done,
but the shunt voltage still can be measured.
As the resistor is externaly connected to the ISL28022 chip there is no default.
When i set default to any value (e.g 1000 micro Ohm), current and power calculation
will give wrong results (except when the shunt _is_ 1000 micro Ohm)

From datasheet table 6 on page 15 there are two similar ADC modes:
3 - without samples
8 - with one? sample
I intended enum 0 to ADC mode 3, 1 to ADC mode 8,
but i can live without ADC mode 3.

As there's no generic yet, replaced with
renesas,average-samples:

Number of samples to be used to report voltage, current and power values.
default: 1
$ref: /schemas/types.yaml#/definitions/uint32-array
enum: [1, 2, 4, 8, 16, 32, 64, 128]

Fixed for [Patch v2], runs without errors or warnings
