-Allwinner sun4i A10 musb DRC/OTG controller
--------------------------------------------
-
-Required properties:
- - compatible : "allwinner,sun4i-a10-musb", "allwinner,sun6i-a31-musb",
- "allwinner,sun8i-a33-musb" or "allwinner,sun8i-h3-musb"
- - reg : mmio address range of the musb controller
- - clocks : clock specifier for the musb controller ahb gate clock
- - reset : reset specifier for the ahb reset (A31 and newer only)
- - interrupts : interrupt to which the musb controller is connected
- - interrupt-names : must be "mc"
- - phys : phy specifier for the otg phy
- - phy-names : must be "usb"
- - dr_mode : Dual-Role mode must be "host" or "otg"
- - extcon : extcon specifier for the otg phy
-
-Example:
-
- usb_otg: usb@1c13000 {
- compatible = "allwinner,sun4i-a10-musb";
- reg = <0x01c13000 0x0400>;
- clocks = <&ahb_gates 0>;
- interrupts = <38>;
- interrupt-names = "mc";
- phys = <&usbphy 0>;
- phy-names = "usb";
- extcon = <&usbphy 0>;
- };

The Allwinner SoCs have an mUSB controller that is supported in Linux, with a matching Device Tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that controller over to a YAML schemas.
