   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
  10
  11 Optional properties:
  12   - reset-gpio:         GPIO spec for the rstn pin
  13   - sleep-gpio:         GPIO spec for the slp_tr pin
  14   - xtal-trim:          u8 value for fine tuning the internal capacitance
  15                         arrays of xtal pins: 0 = +0 pF, 0xf = +4.5 pF

  19         at86rf231@0 {
  20                 compatible = "atmel,at86rf231";
  21                 spi-max-frequency = <7500000>;
  22                 reg = <0>;
  23                 interrupts = <19 1>;
  24                 interrupt-parent = <&gpio3>;
  25                 xtal-trim = /bits/ 8 <0x06>;
  26         };
