Subject: [PATCH 1/2] 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>;
- };
