* 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;
};
