Kernel-4.18.0-80.el8_si4713

• 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>;
    };

};
