extcon: fsa9480: Rewrite bindings in YAML and extend 



This rewrites the FSA9480 DT bindings using YAML and
extends them with the compatible TI TSU6111.

I chose to name the file fcs,fsa880 since this is the
first switch, later versions are improvements.

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 one of

   "fcs,fsa9480"

   "fcs,fsa880"

 - 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>;

	};

  The FSA880 and FSA9480 are USB port accessory detectors and switches.

  The switch is fully controlled using I2C and enables USB data, stereo

  and mono audio, video, microphone, and UART data to use a common

  connector port. Compatible switches exist from other manufacturers.
