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.

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.

It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.
There is a lot of things happening here, but I won't perform review if
the code was never tested. Sorry, please test before sending.
Best regards,
Krzysztof

Hi,
You did not address any of the comments and build issues neither here
nor in previous mailings. Starting from 2022, all previous comments look
ignored and then after some time you send another v1 expecting us to do
review of the same code with the same issues.
I gave it 1 month for some sort of response from you. None came.
Therefore let's be clear: I will automatically NAK any further version
you send, based on assumption you ignored entire existing feedback.
Before sending any new patches for this XSPI, please first respond to
numerous emails you already got (from the last two years). That's way we
will know that reviewer's feedback is being addressed.
Thank you for understanding.
Best regards,
Krzysztof
