    5 Some of them includes an RDS encoder.
    6 
    7 Required Properties:
    8 - compatible: Should contain "silabs,si470x"
    9 - reg: the I2C address of the device
   10 
   11 Optional Properties:
   12 - interrupts : The interrupt number
   13 - reset-gpios: GPIO specifier for the chips reset line
   14 
   15 Example:
   16 
   17 &i2c2 {
   18         si470x@63 {
   19                 compatible = "silabs,si470x";
   20                 reg = <0x63>;
   21 
   22                 interrupt-parent = <&gpj2>;
   23                 interrupts = <4 IRQ_TYPE_EDGE_FALLING>;
   24                 reset-gpios = <&gpj2 5 GPIO_ACTIVE_HIGH>;
