Only enable it I think in the driver.  Should be fine with a stub regulator
as provided if we don't specify one in the dt binding because it's not
controllable and we are lazy.

That shouldn't be here. I have some local changes where I use sel-gpios hence
this include.

My bot found errors running 'make dt_binding_check' on your patch:

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/iio/chemical/sensirion,scd30.example.dt.yaml: scd30@61: 'interrupt-parrent' does not match any of the regexes: 'pinctrl-[0-9]+'
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/iio/chemical/sensirion,scd30.example.dt.yaml: scd30: 'interrupt-parrent' does not match any of the regexes: 'pinctrl-[0-9]+'

See https://patchwork.ozlabs.org/patch/1275131

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.

Well, a typo here.
