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>;
|
||||
};
