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