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.

Huh, why and how?

It's impossible to apply this.

Thanks. Those prerequisite lines were included from b4 after adding the deps:
change-id: 20260108-axiado-ax3000-add-emmc-phy-driver-support-d61aead8f622:v1
base-commit: v6.19-rc4
I'll remove them.

There is one line change in the upcoming latest patch so I didn't add your Acked-by.
