[PATCH v2 5/6] dt-bindings: display: Split common Solomon properties in their own schema
Posted by Javier Martinez Canillas 2 years, 2 months ago
There are DT properties that can be shared across different Solomon OLED
Display Controller families. Split them into a separate common schema to
avoid these properties to be duplicated in different DT bindings schemas.

Yeah, I mention that in the cover letter. That "(no changes since...)"
message is automatically added by the tool I use to post patches (patman)
for all patches that don't have a change history, even for new patches in
a series revision. And I don't know of a way to disable it...

Maybe what I should do is to add a change history to new patches mentioned
that is a new patch to prevent this message to appear.

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:
./Documentation/devicetree/bindings/display/solomon,ssd-common.yaml:42:27: [error] no new line character at the end of file (new-line-at-end-of-file)

dtschema/dtc warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20231012065822.1007930-6-javierm@redhat.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.
