Kernel-4.18.0-80.el8_pn533-i2c

• 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 {

pn532: pn532@24 {

    compatible = "nxp,pn532-i2c";

    reg = <0x24>;
    clock-frequency = <400000>;

    interrupt-parent = <&gpio1>;
    interrupts = <17 IRQ_TYPE_EDGE_FALLING>;

};
