Being a DWMAC derivative, the Tegra234 MGBE supports AXI configuration
nodes named stmmac-axi-config and phandle references to them using the
snps,axi-config property.

While at it, add the 10gbase-r PHY mode.

This gets rid of the remaining warnings on half of the Tegra234 boards.

You should be referencing the whole snps,dwmac.yaml.

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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/net/nvidia,tegra234-mgbe.yaml: properties:snps,axi-config: 'anyOf' conditional failed, one must be fixed:
	'description' is a dependency of '$ref'
	'snps,dwmac.yaml#/properties/snps,axi-config' does not match 'types.yaml#\\/definitions\\/'
		hint: A vendor property needs a $ref to types.yaml
	'snps,dwmac.yaml#/properties/snps,axi-config' does not match '^#\\/(definitions|\\$defs)\\/'
		hint: A vendor property can have a $ref to a a $defs schema
	hint: Vendor specific properties must have a type and description unless they have a defined, common suffix.
	from schema $id: http://devicetree.org/meta-schemas/vendor-props.yaml

doc reference errors (make refcheckdocs):

See https://patchwork.kernel.org/project/devicetree/patch/20260716212001.989872-1-thierry.reding@kernel.org

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

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

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
