[PATCH v2 7/7] dt-bindings: usb: ti,da830-musb: Convert to DT schema

[Bhargav Joshi <j.bhargav.u@gmail.com>]

Convert the TI DA8xx/OMAP-L1x MUSB text bindings to DT schema. Since
DA8xx MUSB node acts as a parent bus for the CPPI41 DMA controller add
required #address-cells, #size-cells, and ranges properties.

-TI DA8xx MUSB
-~~~~~~~~~~~~~
-For DA8xx/OMAP-L1x/AM17xx/AM18xx platforms.
-
-Required properties:
-~~~~~~~~~~~~~~~~~~~~
- - compatible : Should be set to "ti,da830-musb".
-
- - reg: Offset and length of the USB controller register set.
-
- - interrupts: The USB interrupt number.
-
- - interrupt-names: Should be set to "mc".
-
- - dr_mode: The USB operation mode. Should be one of "host", "peripheral" or "otg".
-
- - phys: Phandle for the PHY device
-
- - phy-names: Should be "usb-phy"
-
- - dmas: specifies the dma channels
-
- - dma-names: specifies the names of the channels. Use "rxN" for receive
-   and "txN" for transmit endpoints. N specifies the endpoint number.
-
-Optional properties:
-~~~~~~~~~~~~~~~~~~~~
- - vbus-supply: Phandle to a regulator providing the USB bus power.
-
-Example:
-	usb_phy: usb-phy {
-		compatible = "ti,da830-usb-phy";
-		#phy-cells = <0>;
-	};
-	usb0: usb@200000 {
-		compatible = "ti,da830-musb";
-		reg = <0x00200000 0x1000>;
-		ranges;
-		#address-cells = <1>;
-		#size-cells = <1>;
-		interrupts = <58>;
-		interrupt-names = "mc";
-
-		dr_mode = "host";
-		vbus-supply = <&usb_vbus>;
-		phys = <&usb_phy 0>;
-		phy-names = "usb-phy";
-
-		dmas = <&cppi41dma 0 0 &cppi41dma 1 0
-			&cppi41dma 2 0 &cppi41dma 3 0
-			&cppi41dma 0 1 &cppi41dma 1 1
-			&cppi41dma 2 1 &cppi41dma 3 1>;
-		dma-names =
-			"rx1", "rx2", "rx3", "rx4",
-			"tx1", "tx2", "tx3", "tx4";
-
-
-		cppi41dma: dma-controller@201000 {
-			compatible = "ti,da830-cppi41";
-			reg =  <0x201000 0x1000
-				0x202000 0x1000
-				0x204000 0x4000>;
-			reg-names = "controller", "scheduler", "queuemgr";
-			interrupts = <58>;
-			#dma-cells = <2>;
-			dma-channels = <4>;
-		};
-
-	};
