Subject: [PATCH] dt-bindings: extcon: rt8973a: Convert DT bindings to YAML

Convert the device tree bindings for Richtek RT8973A MUIC to the YAML
format. No functional changes.

I've added Chanwoo Choi as the binding maintainer as he is listed
as the author of the driver for this device; I can change this if
needed.

-* Richtek RT8973A - Micro USB Switch device
-
-The Richtek RT8973A is Micro USB Switch with OVP and I2C interface. The RT8973A
-is a USB port accessory detector and switch that is optimized to protect low
-voltage system from abnormal high input voltage (up to 28V) and supports high
-speed USB operation. Also, RT8973A support 'auto-configuration' mode.
-If auto-configuration mode is enabled, RT8973A would control internal h/w patch
-for USB D-/D+ switching.
-
-Required properties:
-- compatible: Should be "richtek,rt8973a-muic"
-- reg: Specifies the I2C slave address of the MUIC block. It should be 0x14
-- interrupts: Interrupt specifiers for detection interrupt sources.
-
-Example:
-
-	rt8973a@14 {
-		compatible = "richtek,rt8973a-muic";
-		interrupt-parent = <&gpx1>;
-		interrupts = <5 0>;
-		reg = <0x14>;
-	};
