[net-next RFC PATCH 02/14] dt-bindings: net: move PHY modes to common PHY mode types definition

There is a newer version of this series
[net-next RFC PATCH 02/14] dt-bindings: net: move PHY modes to common PHY mode types definition
Posted by Christian Marangi 2 years ago
Move PHY modes from ethernet-controller schema to dedicated common PHY
mode types definition. This is needed to have a centralized place to
define PHY interface mode and permit usage and reference of these modes
in other schemas.

You need a '/' after '#' or it is not a JSON pointer.

Use '$defs'

'definitions' is special in that we don't process it at all. That's 
probably why you ended up with this overly complicated schema below.

But really, there's no need to use $defs or definitions at all here. 
Just put it under 'properties' And move the references up a level (i.e. 
to the node, not a property).

'items' is for arrays, but you just said this is a 'string', not 
'string-array'.

Already covered by the type $ref.

This can all be expressed with just 1 'enum' as it was before.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20231120135041.15259-3-ansuelsmth@gmail.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.
