1TI DA8xx/OMAP-L1xx/AM18xx USB PHY
2
3Required properties:
4 - compatible: must be "ti,da830-usb-phy".
5 - #phy-cells: must be 1.
6
7This device controls the PHY for both the USB 1.1 OHCI and USB 2.0 OTG
8controllers on DA8xx SoCs. Consumers of this device should use index 0 for
9the USB 2.0 phy device and index 1 for the USB 1.1 phy device.
10
11It also requires a "syscon" node with compatible = "ti,da830-cfgchip", "syscon"
12to access the CFGCHIP2 register.

14Example:
15
16	cfgchip: cfgchip@1417c {
17		compatible = "ti,da830-cfgchip", "syscon";
18		reg = <0x1417c 0x14>;
19	};
20
21	usb_phy: usb-phy {
22		compatible = "ti,da830-usb-phy";
23		#phy-cells = <1>;
24	};
25
26	usb20: usb@200000 {
27		compatible = "ti,da830-musb";
28		reg = <0x200000 0x1000>;
29		interrupts = <58>;
30		phys = <&usb_phy 0>;
31		phy-names = "usb-phy";
32	};
33
34	usb11: usb@225000 {
35		compatible = "ti,da830-ohci";
36		reg = <0x225000 0x1000>;
37		interrupts = <59>;
38		phys = <&usb_phy 1>;
39		phy-names = "usb-phy";
40	};
