1* Silicon Labs FM Radio transmitter
2
3The Silicon Labs Si4713 is an FM radio transmitter with receive power scan
4supporting 76-108 MHz. It includes an RDS encoder and has both, a stereo-analog
5and a digital interface, which supports I2S, left-justified and a custom
6DSP-mode format. It is programmable through an I2C interface.

8Required Properties:
9- compatible: Should contain "silabs,si4713"
10- reg: the I2C address of the device
11
12Optional 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
