dt-bindings: net: nfc: s3fwrn5: Convert to dtschema
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. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

-* Samsung S3FWRN5 NCI NFC Controller
-
-Required properties:
-- 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
-- s3fwrn5,fw-gpios: Output GPIO pin used to enter firmware mode and
- sleep/wakeup control

-Example:
-
