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. As they are always present,
make them required as well.

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@1417c {

		compatible = "ti,da830-cfgchip", "syscon";

		reg = <0x1417c 0x14>;

	};



	usb_phy: usb-phy {

		compatible = "ti,da830-usb-phy";

		#phy-cells = <1>;

	};



	usb20: usb@200000 {

		compatible = "ti,da830-musb";

		reg = <0x200000 0x1000>;

		interrupts = <58>;

		phys = <&usb_phy 0>;

		phy-names = "usb-phy";

	};



	usb11: usb@225000 {

		compatible = "ti,da830-ohci";

		reg = <0x225000 0x1000>;

		interrupts = <59>;

		phys = <&usb_phy 1>;

		phy-names = "usb-phy";

	};
