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 - interrupt-parent: phandle for the interrupt gpio controller
8 - interrupts: GPIO interrupt to which the chip is connected
10 Optional SoC Specific Properties:
11 - pinctrl-names: Contains only one value - "default".
12 - pintctrl-0: Specifies the pin control groups used for this controller.
14 Example (for ARM-based BeagleBone with PN532 on I2C2):
22 compatible = "nxp,pn532-i2c";
25 clock-frequency = <400000>;
27 interrupt-parent = <&gpio1>;
28 interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
