1 * NXP Semiconductors PN532 NFC Controller
4 - compatible: Should be "nxp,pn532-i2c" or "nxp,pn533-i2c".
5 - clock-frequency: I²C work frequency.
6 - reg: address on the bus
7 - interrupts: GPIO interrupt to which the chip is connected
9 Optional SoC Specific Properties:
10 - pinctrl-names: Contains only one value - "default".
11 - pintctrl-0: Specifies the pin control groups used for this controller.
13 Example (for ARM-based BeagleBone with PN532 on I2C2):
20 compatible = "nxp,pn532-i2c";
23 clock-frequency = <400000>;
25 interrupt-parent = <&gpio1>;
26 interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
