   1 USB EHCI controllers
   2
   3 Required properties:
   4   - compatible : should be "generic-ehci".
   5   - reg : should contain at least address and length of the standard EHCI
   6     register set for the device. Optional platform-dependent registers
   7     (debug-port or other) can be also specified here, but only after
   8     definition of standard EHCI registers.
   9   - interrupts : one EHCI interrupt should be described here.
  10
  11 Optional properties:
  12  - big-endian-regs : boolean, set this for hcds with big-endian registers
  13  - big-endian-desc : boolean, set this for hcds with big-endian descriptors
  14  - big-endian : boolean, for hcds with big-endian-regs + big-endian-desc
  15  - needs-reset-on-resume : boolean, set this to force EHCI reset after resume
  16  - has-transaction-translator : boolean, set this if EHCI have a Transaction
  17                                 Translator built into the root hub.
  18  - clocks : a list of phandle + clock specifier pairs
  19  - phys : phandle + phy specifier pair
  20  - phy-names : "usb"
  21  - resets : phandle + reset specifier pair
  22
  23 Example (Sequoia 440EPx):
  24     ehci@e0000300 {
  25            compatible = "ibm,usb-ehci-440epx", "usb-ehci";
  26            interrupt-parent = <&UIC0>;
  27            interrupts = <1a 4>;
  28            reg = <0 e0000300 90 0 e0000390 70>;
  29            big-endian;
  30    };
  31
  32 Example (Allwinner sun4i A10 SoC):
  33    ehci0: usb@01c14000 {
  34            compatible = "allwinner,sun4i-a10-ehci", "generic-ehci";
  35            reg = <0x01c14000 0x100>;
  36            interrupts = <39>;
  37            clocks = <&ahb_gates 1>;
  38            phys = <&usbphy 1>;
  39            phy-names = "usb";
  40    };
