* Silicon Labs FM Radio transmitter The Silicon Labs Si4713 is an FM radio transmitter with receive power scan supporting 76-108 MHz. It includes an RDS encoder and has both, a stereo-analog and a digital interface, which supports I2S, left-justified and a custom DSP-mode format. It is programmable through an I2C interface. Required Properties: - compatible: Should contain "silabs,si4713" - reg: the I2C address of the device Optional Properties: - interrupts-extended: Interrupt specifier for the chips interrupt - reset-gpios: GPIO specifier for the chips reset line - vdd-supply: phandle for Vdd regulator - vio-supply: phandle for Vio regulator Example: &i2c2 { fmtx: si4713@63 { compatible = "silabs,si4713"; reg = <0x63>; interrupts-extended = <&gpio2 21 IRQ_TYPE_EDGE_FALLING>; /* 53 */ reset-gpios = <&gpio6 3 GPIO_ACTIVE_HIGH>; /* 163 */ vio-supply = <&vio>; vdd-supply = <&vaux1>; }; };
