On platform IPQ5332, the MDIO address of qca8084 can be programed
when the device tree property "fixup" defined, the clock sequence
needs to be completed before the PHY probeable.

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.

This is a PHY property, so should be in the PHY node. phylib should
then take care of fit.

Please give a better description of this and the next two properties.

The clock frequencies is not relevent here, the driver sets that up.

these fixup flags are for customizing the MDIO address of qca8084 PHY &
PCS and doing the initialization configurations to bring up PHY.

will describe it more detail in the next patch set.

OK, will remove the clock frequency values in the next patch set.

You must describe the items and constrain them per each variant.

No, for multiple reasons. It's gpios first of all. Where do you see such
property? Where is the existing definition?

Then it is "reset-gpios" if this is MDIO. Why do you put phy properties
in MDIO?

Ok, will describe these items one by one in the next patch set.

There are 5 clock items, the first one is the legacy MDIO clock, the
other clocks are new added for ipq5332 platform, will describe it more
clearly in the next patch set.

will remove this property, and update to use the exited PHY GPIO reset.

Hi Krzysztof,
This patch is passed with the following command in my workspace.
i will upgrade and install yamllint to make sure there is no
warning reported anymore.

make dt_bg_check 
DT_SCHEMA_FILES=Documentation/devicetree/bindings/net/qcom,ipq4019-mdio.yaml

OTHER variants. Not this one.

No clue what's this, but no, I do not believe you tested it at all. It's
not about yamllint. It's was not tested. Look at errors reported on
mailing list.

The change here is for the clock number added for the ipq5332 platform,
the other platforms still use only legacy MDIO clock.

so i add minItems  and maxItems, i will check other .yaml files for the
reference.

Then your patch is wrong as I said. You now affect other variants. I
don't quite get your responses. Style of them suggests that you
disagree, but you are not providing any relevant argument.

We still do not know your base and dtschema version.

The clock arguments are provided in the later part as below. i will also
provide more detail clock names for the new added clocks for the ipq5332
platform in description.

The code base is the commit id:

<Add linux-next specific files for 20231114>

The dtschema version is as below.

As i said before, the frequency of the clocks does not matter
here. That appears to be the drivers problem. I assume every board
design, with any sort of PHY, needs the same clock configuration?

Yes, Andrew, no matter what kind of PHY is connected, these clocks are
fix clocks, the clock rates are same as mentioned above, which are the 
SOC clock configurations.
