| 2 | |
| 3 | Required properties: |
| Christophe Ricard | 4ea7cee | 2014-05-20 21:45:04 +0200 | [diff] [blame] | 4 | - compatible: Should be "st,st21nfca_i2c". |
| Christophe Ricard | f517a5f | 2014-05-13 22:03:40 +0200 | [diff] [blame] | 5 | - clock-frequency: I²C work frequency. |
| 6 | - reg: address on the bus |
| 7 | - interrupt-parent: phandle for the interrupt gpio controller |
| 8 | - interrupts: GPIO interrupt to which the chip is connected |
| 9 | - enable-gpios: Output GPIO pin used for enabling/disabling the ST21NFCA |
| 10 | |
| 11 | Optional SoC Specific Properties: |
| 12 | - pinctrl-names: Contains only one value - "default". |
| 13 | - pintctrl-0: Specifies the pin control groups used for this controller. |
| 14 | |
| 15 | Example (for ARM-based BeagleBoard xM with ST21NFCA on I2C2): |
| 16 | |
| 17 | &i2c2 { |
| 18 | |
| 19 | status = "okay"; |
| 20 | |
| 21 | st21nfca: st21nfca@1 { |
| 22 | |
| 23 | compatible = "st,st21nfca_i2c"; |
| 24 | |
| 25 | reg = <0x01>; |
| 26 | clock-frequency = <400000>; |
| 27 | |
| 28 | interrupt-parent = <&gpio5>; |
| 29 | interrupts = <2 IRQ_TYPE_LEVEL_LOW>; |
| 30 | |
| 31 | enable-gpios = <&gpio5 29 GPIO_ACTIVE_HIGH>; |
| 32 | }; |
| 33 | }; |
