1 TI DA8xx/OMAP-L1xx/AM18xx USB PHY
2
3 Required properties:
4  - compatible: must be "ti,da830-usb-phy".
5  - #phy-cells: must be 1.
6
7 This device controls the PHY for both the USB 1.1 OHCI and USB 2.0 OTG
8 controllers on DA8xx SoCs. Consumers of this device should use index 0 for
9 the USB 2.0 phy device and index 1 for the USB 1.1 phy device.
10
11 It also requires a "syscon" node with compatible = "ti,da830-cfgchip", "syscon"
12 to access the CFGCHIP2 register.
13
14 Example:
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";
