dt-bindings: nfc: nxp,nci: convert to dtschema 



Convert the NXP NCI NFC controller to DT schema format.

Drop the "clock-frequency" property during conversion because it is a
property of I2C bus controller, not I2C slave device.  It was also never
used by the driver.

* 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

- interrupts: GPIO interrupt to which the chip is connected

- enable-gpios: Output GPIO pin used for enabling/disabling the chip



Optional SoC Specific Properties:

- pinctrl-names: Contains only one value - "default".

- pintctrl-0: Specifies the pin control groups used for this controller.

- firmware-gpios: Output GPIO pin used to enter firmware download mode



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



&i2c2 {





	npc100: npc100@29 {



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



		reg = <0x29>;

		clock-frequency = <100000>;



		interrupt-parent = <&gpio1>;

		interrupts = <29 IRQ_TYPE_LEVEL_HIGH>;



		enable-gpios = <&gpio0 30 GPIO_ACTIVE_HIGH>;

		firmware-gpios = <&gpio0 31 GPIO_ACTIVE_HIGH>;

	};
