1 | * Silicon Labs FM Radio transmitter | ||
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 | |||
