+* 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;
+       };
