+- compatible: Should be
+ - "nxp,pn532" Place a node with this inside the devicetree node of the bus
+ where the NFC chip is connected to.
+ Currently the kernel has phy bindings for uart and i2c.
+ - "nxp,pn532-i2c" (DEPRECATED) only works for the i2c binding.
+ - "nxp,pn533-i2c" (DEPRECATED) only works for the i2c binding.
+
+Required properties if connected on i2c:
- clock-frequency: I²C work frequency.
-- reg: address on the bus
+- reg: for the I²C bus address. This is fixed at 0x24 for the PN532.
- interrupts: GPIO interrupt to which the chip is connected
