		* 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>;
		};
		};
