This patch need depend on

then the spi yaml file will build successful, if no this clock patch 
that spi yaml will build fail, so please test it that base on above 
clock patch.

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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Error: Documentation/devicetree/bindings/spi/loongson,ls-spi.example.dts:22.28-29 syntax error
FATAL ERROR: Unable to parse input tree
make[1]: *** [scripts/Makefile.lib:419: Documentation/devicetree/bindings/spi/loongson,ls-spi.example.dtb] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [Makefile:1512: dt_binding_check] Error 2

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230328112210.23089-2-zhuyinbo@loongson.cn

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 patch need depend on
https://lore.kernel.org/all/20230323025229.2971-1-zhuyinbo@loongson.cn/
then the spi yaml file will build successful. That changelog had record it.

Thus it cannot be merged now. Do not resend it till dependency hits
mainline (since you decided not to go with Rob's advice).

Best regards,
Krzysztof

You decided not to use Rob's advice, thus this patch cannot be applied
now. Wait for the merge window to finish (so dependency is in mainline)
and send the patch then. Not earlier.

Best regards,
Krzysztof

Hi Rob,

I'm sorry, actually, I don't know what the specific operation I should 
do when I received the check warning
from your bot. Does it means that I should add dependency note into this 
patch's changelog ? or something else, I really
don't know. Actually, I'm always bothered by these things that how to 
resolve the dependency issue for two
dependent patches that do not belong to the same series.

Thanks.

Yes, this is explicitly mentioned in the sentence you quoted.

Another approach, as Rob suggested last time, would be to just get rid
of the dependency and open-code the clock IDs...

Best regards,
Krzysztof

Thank you very much for your suggestion,  I will open-code the clock
IDs and fix that checkpatch issue then resend this series patch.
