3The Silicon Labs Si470x is family of FM radio receivers with receive power scan
4supporting 76-108 MHz, programmable through an I2C interface.
5Some of them includes an RDS encoder.

7Required Properties:
8- compatible: Should contain "silabs,si470x"
9- reg: the I2C address of the device
10
11Optional Properties:
12- interrupts : The interrupt number
13- reset-gpios: GPIO specifier for the chips reset line

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>;
25        };
