[PATCH net-next v5 14/14] dt-bindings: net: add Microchip's LAN865X 10BASE-T1S MACPHY
Posted by Parthiban Veerasooran 1 month, 3 weeks ago
The LAN8650/1 combines a Media Access Controller (MAC) and an Ethernet
PHY to enable 10BASE-T1S networks. The Ethernet Media Access Controller
(MAC) module implements a 10 Mbps half duplex Ethernet MAC, compatible
with the IEEE 802.3 standard and a 10BASE-T1S physical layer transceiver
integrated into the LAN8650/1. The communication between the Host and the
MAC-PHY is specified in the OPEN Alliance 10BASE-T1x MACPHY Serial
Interface (TC6).

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/microchip,lan8650.yaml: $id: Cannot determine base path from $id, relative path/filename doesn't match actual path or filename
 	 $id: http://devicetree.org/schemas/net/microchip,lan865x.yaml
 	file: /builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/net/microchip,lan8650.yaml

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240726123907.566348-15-Parthiban.Veerasooran@microchip.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.

Sorry, somehow I missed it. Thanks for letting me know. Will fix it 
while reposting the patch series as the windows is closed now.
