FAIRCHILD SEMICONDUCTOR FSA9480 MICROUSB SWITCH
The FSA9480 is a USB port accessory detector and switch. The FSA9480 is fully
controlled using I2C and enables USB data, stereo and mono audio, video,
microphone, and UART data to use a common connector port.
Required properties:
- compatible : Must be "fcs,fsa9480"
- reg : Specifies i2c slave address. Must be 0x25.
- interrupts : Should contain one entry specifying interrupt signal of
interrupt parent to which interrupt pin of the chip is connected.
Example:
musb@25 {
compatible = "fcs,fsa9480";
reg = <0x25>;
interrupt-parent = <&gph2>;
interrupts = <7 0>;
};
