   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";
  40         };
