|  | * AT86RF230 IEEE 802.15.4 * | 
|  |  | 
|  | Required properties: | 
|  | - compatible:		should be "atmel,at86rf230", "atmel,at86rf231", | 
|  | "atmel,at86rf233" or "atmel,at86rf212" | 
|  | - spi-max-frequency:	maximal bus speed, should be set to 7500000 depends | 
|  | sync or async operation mode | 
|  | - reg:		the chipselect index | 
|  | - interrupts:		the interrupt generated by the device. Non high-level | 
|  | can occur deadlocks while handling isr. | 
|  |  | 
|  | Optional properties: | 
|  | - reset-gpio:		GPIO spec for the rstn pin | 
|  | - sleep-gpio:		GPIO spec for the slp_tr pin | 
|  | - xtal-trim:		u8 value for fine tuning the internal capacitance | 
|  | arrays of xtal pins: 0 = +0 pF, 0xf = +4.5 pF | 
|  |  | 
|  | Example: | 
|  |  | 
|  | at86rf231@0 { | 
|  | compatible = "atmel,at86rf231"; | 
|  | spi-max-frequency = <7500000>; | 
|  | reg = <0>; | 
|  | interrupts = <19 4>; | 
|  | interrupt-parent = <&gpio3>; | 
|  | xtal-trim = /bits/ 8 <0x06>; | 
|  | }; |
