1* NXP Semiconductors PN532 NFC Controller
2
3Required properties:
4- compatible: Should be "nxp,pn532-i2c" or "nxp,pn533-i2c".
5- clock-frequency: I²C work frequency.
6- reg: address on the bus
7- interrupt-parent: phandle for the interrupt gpio controller
8- interrupts: GPIO interrupt to which the chip is connected
9
10Optional SoC Specific Properties:
11- pinctrl-names: Contains only one value - "default".
12- pintctrl-0: Specifies the pin control groups used for this controller.

14Example (for ARM-based BeagleBone with PN532 on I2C2):
15
16&i2c2 {
17
18 status = "okay";
19
20 pn532: pn532@24 {
21
22 compatible = "nxp,pn532-i2c";
23
24 reg = <0x24>;
25 clock-frequency = <400000>;
26
27 interrupt-parent = <&gpio1>;
28 interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
29
30 };
31};
