-* 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>;
