[PATCH] spi: dt-bindings: mediatek,spi-mtk-nor: Add clock bindings for mt8189

[Meiker Gao]

Update mediatek,spi-mtk-nor.yaml to add conditional clock and
clock-names bindings for the mt8189-nor platform. The mt8189-nor
controller requires five specific clocks and corresponding clock-names
("spi", "sf", "axi_f", "axi_h", "axi_p"). This change enforces these
requirements in the device tree binding schema.

For other platforms, the minimum number of clocks and clock-names
remains unchanged. The patch also adds an example for mt8189-nor,
illustrating the new clock configuration.

This update ensures correct hardware description and validation for
mt8189-nor, improving compatibility and reducing configuration errors.

That's just axi, no? Thus keep the list in top-level.

And that's axi_s

And what does p stand for? Do you understand these are names of clock
inputs, not names of clocks?

And that's ABI change, NAK.

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

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.

[PATCH] spi: dt-bindings: mediatek,spi-mtk-nor: Add clock bindings for mt8189

[Meiker Gao]

Update mediatek,spi-mtk-nor.yaml to add conditional clock and
clock-names bindings for the mt8189-nor platform. The mt8189-nor
controller requires five specific clocks and corresponding clock-names
("spi", "sf", "axi_f", "axi_h", "axi_p"). This change enforces these
requirements in the device tree binding schema.

For other platforms, the minimum number of clocks and clock-names
remains unchanged. The patch also adds an example for mt8189-nor,
illustrating the new clock configuration.

This update ensures correct hardware description and validation for
mt8189-nor, improving compatibility and reducing configuration errors.

pip3 install dtschema --upgrade

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.

No, I don't understand why you remove names. This is not expected.
Please also read writing schema and writing bindings docs explaining how
to organize properties with variable lengths. There is plenty of
examples to follow.

Pointess. Drop.

ABI change without explanation. Don't mix multiple changes into one
commit.

Plain wrong. So either 2 or 4.

No, drop entire example.

Also commit msg is incorrect - you are not adding clock bindings.

And there is no user of this, so entire patch is pointless and should
not be sent. We don't take unused bindings.
