* NXP Semiconductors PN544 NFC Controller
Required properties:
- compatible: Should be "nxp,pn544-i2c".
- clock-frequency: I²C work frequency.
- reg: address on the bus
- interrupts: GPIO interrupt to which the chip is connected
- enable-gpios: Output GPIO pin used for enabling/disabling the PN544
- firmware-gpios: Output GPIO pin used to enter firmware download mode
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 PN544 on I2C2):
&i2c2 {
pn544: pn544@28 {
compatible = "nxp,pn544-i2c";
reg = <0x28>;
clock-frequency = <400000>;
interrupt-parent = <&gpio1>;
interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;
enable-gpios = <&gpio3 21 GPIO_ACTIVE_HIGH>;
firmware-gpios = <&gpio3 19 GPIO_ACTIVE_HIGH>;
};
};
