[PATCH 1/4] dt-bindings: net: nfc: s3fwrn5: Convert to dtschema

[Krzysztof Kozlowski <krzk@kernel.org>]

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.

-* 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:
-
-&hsi2c_4 {
-	s3fwrn5@27 {
-		compatible = "samsung,s3fwrn5-i2c";
-
-		reg = <0x27>;
-
-		interrupt-parent = <&gpa1>;
-		interrupts = <3 0 0>;
-
-		s3fwrn5,en-gpios = <&gpf1 4 0>;
-		s3fwrn5,fw-gpios = <&gpj0 2 0>;
-	};
