-* 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>;
- };
-};
