1* Marvell International Ltd. NCI NFC Controller
2
3Required properties:
4- compatible: Should be:
5  - "marvell,nfc-uart" or "mrvl,nfc-uart" for UART devices
6  - "marvell,nfc-i2c" for I2C devices
7  - "marvell,nfc-spi" for SPI devices
8
9Optional SoC specific properties:
10- pinctrl-names: Contains only one value - "default".
11- pintctrl-0: Specifies the pin control groups used for this controller.
12- reset-n-io: Output GPIO pin used to reset the chip (active low).
13- hci-muxed: Specifies that the chip is muxing NCI over HCI frames.
14
15Optional UART-based chip specific properties:
16- flow-control: Specifies that the chip is using RTS/CTS.
17- break-control: Specifies that the chip needs specific break management.
18
19Optional I2C-based chip specific properties:
20- i2c-int-falling: Specifies that the chip read event shall be trigged on
21  		   falling edge.
22- i2c-int-rising: Specifies that the chip read event shall be trigged on
23  		  rising edge.

29
30	nfcmrvluart: nfcmrvluart@5 {
31		compatible = "marvell,nfc-uart";
32
33		reset-n-io = <&gpio3 16 0>;
34
35		hci-muxed;
36		flow-control;
37        }
38};

46
47	nfcmrvli2c0: i2c@1 {
48		compatible = "marvell,nfc-i2c";
49
50		reg = <0x8>;
51
52		/* I2C INT configuration */
