Subject: [PATCH] dt-bindings: phy: Convert ti,da830-usb-phy to DT schema
Convert the TI DA830 USB PHY binding to DT schema format. Add "clocks"
and "clock-names" which are already in use.

-TI DA8xx/OMAP-L1xx/AM18xx USB PHY
-
-Required properties:
- - compatible: must be "ti,da830-usb-phy".
- - #phy-cells: must be 1.
-
-This device controls the PHY for both the USB 1.1 OHCI and USB 2.0 OTG
-controllers on DA8xx SoCs. Consumers of this device should use index 0 for
-the USB 2.0 phy device and index 1 for the USB 1.1 phy device.
-
-It also requires a "syscon" node with compatible = "ti,da830-cfgchip", "syscon"
-to access the CFGCHIP2 register.
-
-Example:
-
- cfgchip: cfgchip@...7c {
- compatible = "ti,da830-cfgchip", "syscon";
- reg = <0x1417c 0x14>;
- };
-
- usb_phy: usb-phy {
- compatible = "ti,da830-usb-phy";
- #phy-cells = <1>;
- };
-
- usb20: usb@...000 {
- compatible = "ti,da830-musb";
- reg = <0x200000 0x1000>;
- interrupts = <58>;
- phys = <&usb_phy 0>;
- phy-names = "usb-phy";
- };
-
- usb11: usb@...000 {
- compatible = "ti,da830-ohci";
- reg = <0x225000 0x1000>;
- interrupts = <59>;
- phys = <&usb_phy 1>;
- phy-names = "usb-phy";
