* Marvell International Ltd. NCI NFC Controller

Required properties:
- compatible: Should be "mrvl,nfc-uart".

Optional SoC specific properties:
- pinctrl-names: Contains only one value - "default".
- pintctrl-0: Specifies the pin control groups used for this controller.
- reset-n-io: Output GPIO pin used to reset the chip (active low).
- hci-muxed: Specifies that the chip is muxing NCI over HCI frames.

Optional UART-based chip specific properties:
- flow-control: Specifies that the chip is using RTS/CTS.
- break-control: Specifies that the chip needs specific break management.

Example (for ARM-based BeagleBoard Black with 88W8887 on UART5):

&uart5 {
	status = "okay";

	nfcmrvluart: nfcmrvluart@5 {
		compatible = "mrvl,nfc-uart";

		reset-n-io = <&gpio3 16 0>;

		hci-muxed;
		flow-control;
        }
};
