* NXP Semiconductors NXP NCI NFC Controllers

Required properties:
- compatible: Should be "nxp,nxp-nci-i2c".
- clock-frequency: I²C work frequency.
- reg: address on the bus
- interrupt-parent: phandle for the interrupt gpio controller
- interrupts: GPIO interrupt to which the chip is connected
- enable-gpios: Output GPIO pin used for enabling/disabling the chip
- firmware-gpios: Output GPIO pin used to enter firmware download mode

Optional SoC Specific Properties:
- pinctrl-names: Contains only one value - "default".
- pintctrl-0: Specifies the pin control groups used for this controller.

Example (for ARM-based BeagleBone with NPC100 NFC controller on I2C2):

&i2c2 {

	status = "okay";

	npc100: npc100@29 {

		compatible = "nxp,nxp-nci-i2c";

		reg = <0x29>;
		clock-frequency = <100000>;

		interrupt-parent = <&gpio1>;
		interrupts = <29 GPIO_ACTIVE_HIGH>;

		enable-gpios = <&gpio0 30 GPIO_ACTIVE_HIGH>;
		firmware-gpios = <&gpio0 31 GPIO_ACTIVE_HIGH>;
	};
};
