* 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>;
|
|
};
|
|
};
