Posted by Martin Kurbanov 2 years, 10 months ago
Add YAML devicetree Amlogic Meson A113L (A1 family) SPIFC Driver.

This patch has dependencies on the A1 clock series which is still under
review - https://lore.kernel.org/all/20230321193014.26349-1-ddrokosov@sberdevices.ru/

I think it's time to drop "Meson" from bindings, please drop Meson here and in all the file
down to the compatible which should be "amlogic,a1-spifc"

Drop the include and use fake label phandles instead.

Don't add drivers to DT bindings.

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

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230327211351.686831-2-mmkurbanov@sberdevices.ru

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.
