* 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>;
|
|
|
|
};
|
|
};
