+Required properties:
+ - compatible: should be "microchip,mrf24j40", "microchip,mrf24j40ma",
+ or "microchip,mrf24j40mc" depends on your transceiver
+ board
+ - spi-max-frequency: maximal bus speed, should be set something under or equal
+ 10000000
+ - reg: the chipselect index
+ - interrupts: the interrupt generated by the device.
+
+Example:
+
+ mrf24j40ma@0 {
+ compatible = "microchip,mrf24j40ma";
+ spi-max-frequency = <8500000>;
+ reg = <0>;
+ interrupts = <19 8>;
+ interrupt-parent = <&gpio3>;
+ };
