[PATCH v2 04/12] dt-bindings: net: starfive,jh7110-dwmac: Add JH7100 SoC compatible
Posted by Cristian Ciocaltea 2 years, 1 month ago
The Synopsys DesignWare MAC found on StarFive JH7100 SoC is quite
similar to the newer JH7110, but it requires only two interrupts and a
single reset line.

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20231029042712.520010-5-cristian.ciocaltea@collabora.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.

And here you have proof of missing testing of patch #2.

Why do you use different fallback?

You just changed it in previous patches... So the previous code allowing
one item was correct?

AFAIK, dwmac-5.20 is currently only used by JH7110.

I mentioned the possible use-cases in the previous email. So yes, JH7110
requires 2 resets, while JH7100 just one.

What is used by JH7000?

Your previous patch does not make sense now...

Driver reports "Synopsys ID: 0x37", so it could be 3.70a or 3.710, as
those are the only compatibles available for 3.7x.

It's worth noting the driver does not rely on the compatibles for
implementing version specific logic, as it gets the IDs directly from
chip registers.

The usage of generic snps,dwmac fallback was borrowed from downstream code.
