+* 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
+
+Optional properties:
+  - reset-gpio:         GPIO spec for the rstn pin
+  - sleep-gpio:         GPIO spec for the slp_tr pin
+
+Example:
+
+        at86rf231@0 {
+                compatible = "atmel,at86rf231";
+                spi-max-frequency = <7500000>;
+                reg = <0>;
+                interrupts = <19 1>;
+                interrupt-parent = <&gpio3>;
+        };
