[PATCH] dt-bindings: watchdog: alphascale-asm9260: convert to DT schema

[Om Parikh]

this patch replaces the txt file and adds YAML bindings file
adhering to the json-schema for alphascale-asm9260. It is a
demo patch for potential further contributions to the GSOC
project.

Do not use "This commit/patch", but imperative mood. See:
https://elixir.bootlin.com/linux/v5.17.1/source/Documentation/process/submitting-patches.rst#L95

Use full sentences, so start with capital letter.

Drop unrelated messages.

Drop, not related to Linux kernel.

Anyway, send your patches first through you mentor, so we won't have to
comment on trivial things.


Daniel,
Are you doing a review of your mentees?

NAK, this does not make any sense. I don't understand what do you want
to document here. These are boards.

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:

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.

[PATCH] dt-bindings: watchdog: alphascale-asm9260: convert to DT schema

[Om Parikh]

Thanks for the feedback, I have incorporated the fixes in the patch. Warnings generated from `checkpatch.pl` script seems to be false positive in this case.

Do not attach (thread) your patchsets to some other threads (unrelated
or older versions). This buries them deep in the mailbox and might
interfere with applying entire sets.

This is the same patch you already sent, so a resend? Sorry, I am not
going to review again. You got comments. If this is v2, then send a v2
with changelog.

Best regards,
Krzysztof
