1 * NXP Semiconductors PN532 NFC Controller
4 - compatible: Should be
5 - "nxp,pn532" Place a node with this inside the devicetree node of the bus
6 where the NFC chip is connected to.
7 Currently the kernel has phy bindings for uart and i2c.
8 - "nxp,pn532-i2c" (DEPRECATED) only works for the i2c binding.
9 - "nxp,pn533-i2c" (DEPRECATED) only works for the i2c binding.
11 Required properties if connected on i2c:
12 - clock-frequency: I²C work frequency.
13 - reg: for the I²C bus address. This is fixed at 0x24 for the PN532.
14 - interrupts: GPIO interrupt to which the chip is connected
17 - pinctrl-names: Contains only one value - "default".
18 - pintctrl-0: Specifies the pin control groups used for this controller.
20 Example (for ARM-based BeagleBone with PN532 on I2C2):
25 pn532: nfc@24 {
30 clock-frequency = <400000>;
32 interrupt-parent = <&gpio1>;
41 compatible = "ti,omap3-uart";
43 pn532: nfc {
