Dpn532.txt1 * NXP Semiconductors PN532 NFC Controller
5 - "nxp,pn532" Place a node with this inside the devicetree node of the bus
8 - "nxp,pn532-i2c" (DEPRECATED) only works for the i2c binding.
13 - reg: for the I²C bus address. This is fixed at 0x24 for the PN532.
20 Example (for ARM-based BeagleBone with PN532 on I2C2):
25 pn532: nfc@24 {
27 compatible = "nxp,pn532";
38 Example (for PN532 connected via uart):
43 pn532: nfc {
44 compatible = "nxp,pn532";
