+* CA8210 IEEE 802.15.4 *
+
+Required properties:
+	- compatible:           Should be "cascoda,ca8210"
+	- reg:                  Controlling chip select
+	- spi-max-frequency:    Maximum clock speed, should be *less than*
+	                        4000000
+	- spi-cpol:             Requires inverted clock polarity
+	- reset-gpio:           GPIO attached to reset
+	- irq-gpio:             GPIO attached to IRQ
+Optional properties:
+	- extclock-enable:      Include for the ca8210 to route its 16MHz clock
+	                        to an output
+	- extclock-freq:        Frequency in Hz of the external clock
+	- extclock-gpio:        GPIO of the ca8210 to output the clock on
+
+Example:
+	ca8210@0 {
+		compatible = "cascoda,ca8210";
+		reg = <0>;
+		spi-max-frequency = <3000000>;
+		spi-cpol;
+		reset-gpio = <&gpio1 1 GPIO_ACTIVE_HIGH>;
+		irq-gpio = <&gpio1 2 GPIO_ACTIVE_HIGH>;
+		extclock-enable;
+		extclock-freq = 16000000;
+		extclock-gpio = 2;
+	};
