| 2 | |
| 3 | Required properties: |
| 4 | - compatible: should be "atmel,at86rf230", "atmel,at86rf231", |
| 5 | "atmel,at86rf233" or "atmel,at86rf212" |
| 6 | - spi-max-frequency: maximal bus speed, should be set to 7500000 depends |
| 7 | sync or async operation mode |
| 8 | - reg: the chipselect index |
| 9 | - interrupts: the interrupt generated by the device. Non high-level |
| 10 | can occur deadlocks while handling isr. |
| 11 | |
| 12 | Optional properties: |
| 13 | - reset-gpio: GPIO spec for the rstn pin |
| 14 | - sleep-gpio: GPIO spec for the slp_tr pin |
| 15 | - xtal-trim: u8 value for fine tuning the internal capacitance |
| 16 | arrays of xtal pins: 0 = +0 pF, 0xf = +4.5 pF |
| 17 | |
| 18 | Example: |
| 19 | |
| 20 | at86rf231@0 { |
| 21 | compatible = "atmel,at86rf231"; |
| 22 | spi-max-frequency = <7500000>; |
| 23 | reg = <0>; |
| 24 | interrupts = <19 4>; |
| 25 | interrupt-parent = <&gpio3>; |
| 26 | xtal-trim = /bits/ 8 <0x06>; |
| 27 | }; |
