| 2 | |
| 3 | The Silicon Labs Si4713 is an FM radio transmitter with receive power scan |
| 4 | supporting 76-108 MHz. It includes an RDS encoder and has both, a stereo-analog |
| 5 | and a digital interface, which supports I2S, left-justified and a custom |
| 6 | DSP-mode format. It is programmable through an I2C interface. |
| 7 | |
| 8 | Required Properties: |
| 9 | - compatible: Should contain "silabs,si4713" |
| 10 | - reg: the I2C address of the device |
| 11 | |
| 12 | Optional Properties: |
| 13 | - interrupts-extended: Interrupt specifier for the chips interrupt |
| 14 | - reset-gpios: GPIO specifier for the chips reset line |
| 15 | - vdd-supply: phandle for Vdd regulator |
| 16 | - vio-supply: phandle for Vio regulator |
| 17 | |
| 18 | Example: |
| 19 | |
| 20 | &i2c2 { |
| 21 | fmtx: si4713@63 { |
| 22 | compatible = "silabs,si4713"; |
| 23 | reg = <0x63>; |
| 24 | |
| 25 | interrupts-extended = <&gpio2 21 IRQ_TYPE_EDGE_FALLING>; /* 53 */ |
| 26 | reset-gpios = <&gpio6 3 GPIO_ACTIVE_HIGH>; /* 163 */ |
| 27 | vio-supply = <&vio>; |
| 28 | vdd-supply = <&vaux1>; |
| 29 | }; |
| 30 | }; |
