+* 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>;
