* Silicon Labs FM Radio receiver



The Silicon Labs Si470x is family of FM radio receivers with receive power scan

supporting 76-108 MHz, programmable through an I2C interface.

Some of them includes an RDS encoder.



Required Properties:

- compatible: Should contain "silabs,si470x"

- reg: the I2C address of the device



Optional Properties:

- interrupts : The interrupt number

- reset-gpios: GPIO specifier for the chips reset line



Example:



&i2c2 {

        si470x@63 {

                compatible = "silabs,si470x";

                reg = <0x63>;



                interrupt-parent = <&gpj2>;

                interrupts = <4 IRQ_TYPE_EDGE_FALLING>;

                reset-gpios = <&gpj2 5 GPIO_ACTIVE_HIGH>;

        };

};
