* Samsung S3FWRN5 NCI NFC Controller

Required properties:
- compatible: Should be "samsung,s3fwrn5-i2c".
- reg: address on the bus
- interrupt-parent: phandle for the interrupt gpio controller
- 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 {
	status = "okay";
	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>;
	};
};
