* NXP Semiconductors PN532 NFC Controller
Required properties:
- compatible: Should be "nxp,pn532-i2c" or "nxp,pn533-i2c".
- clock-frequency: I²C work frequency.
- reg: address on the bus
- interrupt-parent: phandle for the interrupt gpio controller
- interrupts: GPIO interrupt to which the chip is connected
Optional SoC Specific Properties:
- pinctrl-names: Contains only one value - "default".
- pintctrl-0: Specifies the pin control groups used for this controller.
Example (for ARM-based BeagleBone with PN532 on I2C2):
&i2c2 {
status = "okay";
pn532: pn532@24 {
compatible = "nxp,pn532-i2c";
reg = <0x24>;
clock-frequency = <400000>;
interrupt-parent = <&gpio1>;
interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
