[PATCH V1 1/3] dt-bindings: ufs: qcom: Document ice configuration table
Posted by Ram Kumar Dwivedi 1 month, 3 weeks ago 
There are three algorithms supported for inline crypto engine:
Floor based, Static and Instantaneous algorithm.

Document the compatible used for the algorithm configurations
for inline crypto engine found.

Three people developed the code, but none of them cared to test it? Or
make it even slightly correct?

Sorry, this code is not ready for upstream. Please work internally on
doing meaningful review and basic tests BEFORE posting.

Best regards,
Krzysztof

No.  The algorithms supported by ICE are AES-XTS, AES-ECB, AES-CBC, etc.  So I'm
afraid this terminology is already taken.

This new thing seems to be about how work is distributed among different
hardware cores, so calling these "ICE schedulers" or something might make sense.

Hi Eric,
	I have rephrased patch commit description. Used terminology as ICE allocator instead of ICE algorithm.
Thanks,
Ram.

Examples should be enabled.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/ufs/qcom,ufs.example.dtb: alg3: status: 'oneOf' conditional failed, one must be fixed:
	['ok'] is not of type 'object'
	'ok' is not one of ['okay', 'disabled', 'reserved', 'fail', 'fail-needs-probe']
	from schema $id: http://devicetree.org/schemas/dt-core.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20241005064307.18972-2-quic_rdwivedi@quicinc.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.

Hi Rob,
	I have addressed the comment in the latest patch set. Now the dt binding is successfully compiling.
Thanks,
Ram.
