+* 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;
+ };
