will change patch order when I send a v2.
Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.
There is no file extension in prefixes.
So: dt-bindings: iio/adc: nxp,imx93-adc: Add calibration properties?
Did you run the command I proposed? I don't see much of "/", but except
that looks good.
Ok noted.

No, use existing, generic properties. Open other bindings for this.
You mean I should use generic properties for the ADC calibration
settings? Is there already something in place? Because as I understand
it, these calib-* values only effect the calibration process of the ADC.
Please take a look at other devices and dtschema. We already have some
properties for this... but maybe they cannot be used?
I did look into other ADC devices, grep across iio/adc, adc bindings
folders and couldn't find anything closely related to what we are
looking for. Could you please point me to the properties that you think
should be used for this?
Thank you.
Andrej
Best regards,
Krzysztof
