-* NXP Semiconductors PN532 NFC Controller
-
-Required properties:
-- 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: for the I²C bus address. This is fixed at 0x24 for the PN532.
-- 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 {
-
-
- pn532: nfc@24 {
-
- compatible = "nxp,pn532";
-
- reg = <0x24>;
- clock-frequency = <400000>;
-
- interrupt-parent = <&gpio1>;
- interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
-
- };
-};
-
-Example (for PN532 connected via uart):
-
-uart4: serial@49042000 {
- compatible = "ti,omap3-uart";
-
- pn532: nfc {
- compatible = "nxp,pn532";
- };
-};
