| 2 | |
| 3 | Required properties: |
| 4 | - compatible: Should be "nxp,pn532-i2c" or "nxp,pn533-i2c". |
| 5 | - clock-frequency: I²C work frequency. |
| 6 | - reg: address on the bus |
| Michael Thalmeier | 71c08ea | 2016-04-11 16:36:02 +0200 | [diff] [blame] | 7 | - interrupts: GPIO interrupt to which the chip is connected |
| 8 | |
| 9 | Optional SoC Specific Properties: |
| 10 | - pinctrl-names: Contains only one value - "default". |
| 11 | - pintctrl-0: Specifies the pin control groups used for this controller. |
| 12 | |
| 13 | Example (for ARM-based BeagleBone with PN532 on I2C2): |
