| * 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>; |
| }; |
| }; |
