[PATCH v2 net-next 1/4] dt-bindings: net: nfc: s3fwrn5: Support a UART interface

[PATCH v2 net-next 1/4] dt-bindings: net: nfc: s3fwrn5: Support a UART interface

[Bongsu jeon]

From: Bongsu Jeon <bongsu.jeon@samsung.com>

Since S3FWRN82 NFC Chip, The UART interface can be used.
S3FWRN82 supports I2C and UART interface.

Signed-off-by: Bongsu Jeon <bongsu.jeon@samsung.com>

Changes in v2:
 -change the compatible name.
 -change the const to enum for compatible.
 -change the node name to nfc.

All patches in the series should have the same version.

If the patch was not changes in the given repost you can add:

 v3:
  - no change

Or just not mention the version in the changelog.

It's also best to provide a cover letter describing what the series
does as a whole for series with more than 2 patches.

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

yamllint warnings/errors:
./Documentation/devicetree/bindings/net/nfc/samsung,s3fwrn5.yaml:17:9: [warning] wrong indentation: expected 10 but found 8 (indentation)

dtschema/dtc warnings/errors:


See https://patchwork.ozlabs.org/patch/1408172

The base for the patch is generally the last rc1. Any dependencies
should be noted.

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.

Don't need 'oneOf' here.

Beside that I received just 1/4 of v2. LKML has one as well:
https://lore.kernel.org/lkml/1606737627-29485-1-git-send-email-bongsu.jeon@samsung.com/

Where are the others?

Best regards,
