[PATCH v2 1/9] dt-bindings: net: nfc: s3fwrn5: Convert to dtschema

[-- Attachment #1: Type: text/plain, Size: 3750 bytes --]

Convert the Samsung S3FWRN5 NCI NFC controller bindings to dtschema.
This is conversion only so it includes properties with invalid prefixes
(s3fwrn5,en-gpios) which should be addressed later.

-- compatible: Should be "samsung,s3fwrn5-i2c".
-- reg: address on the bus
-- interrupts: GPIO interrupt to which the chip is connected
-- s3fwrn5,en-gpios: Output GPIO pin used for enabling/disabling the chip
