+driver cc1101 Low-Power Sub-1 GHz RF Transceiver chip from Texas
+Instruments.
+
+Requires node properties:
+- compatible : should be "ti,cc1101";
+- reg : Chip select address of device, see:
+ Documentation/devicetree/bindings/spi/spi-bus.txt
+- gpios : list of 2 gpios, first gpio is for GDO0 pin
+ second for GDO2 pin, see more:
+ Documentation/devicetree/bindings/gpio/gpio.txt
+
+Recommended properties:
+ - spi-max-frequency: Definition as per
+ Documentation/devicetree/bindings/spi/spi-bus.txt
+ - freq : used spi frequency for communication with cc1101 chip
+
+example:
+
+&ecspi4 {
+ cc1101@0 {
+ compatible = "ti,cc1101";
+ spi-max-frequency = <10000000>;
+ reg = <0>;
+ freq = <5000000>;
+ gpios = <&gpio2 11 GPIO_ACTIVE_HIGH &gpio5 8 GPIO_ACTIVE_HIGH>;
+ };
+};
