[PATCH net-next] dt-bindings: net: micrel: Fix dtbs compatible too long warnings
Posted by Biju 5 days, 7 hours ago 
From: Biju Das <biju.das.jz@bp.renesas.com>

The KSZ9131 PHY is suitable for IEEE 802.3 applications.

Fix the below dtbs warning "compatible: ['ethernet-phy-id0022.1640',
'ethernet-phy-ieee802.3-c22'] is too long" on the below dts:

To avoid the errors, you would need a custom 'select' that excludes
the c22 compatible from this schema (IOW, lists all the other
compatibles here).

However, I think the correct fix is probably dropping the c22
compatible from your .dts files. I don't that compatible is useful on
its own?

Also, it doesn't make sense that ethernet-phy-id0022.1640 is sometimes
compatible with ethernet-phy-ieee802.3-c22 and sometimes isn't.

doc reference errors (make refcheckdocs):

See https://patchwork.kernel.org/project/devicetree/patch/20260203121723.312336-1-biju.das.jz@bp.renesas.com

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.
