   1 PXA USB controllers
   2
   3 OHCI
   4
   5 Required properties:
   6  - compatible: Should be "marvell,pxa-ohci" for USB controllers
   7    used in host mode.
   8
   9 Optional properties:
  10  - "marvell,enable-port1", "marvell,enable-port2", "marvell,enable-port3"
  11    If present, enables the appropriate USB port of the controller.
  12  - "marvell,port-mode" selects the mode of the ports:
  13         1 = PMM_NPS_MODE
  14         2 = PMM_GLOBAL_MODE
  15         3 = PMM_PERPORT_MODE
  16  - "marvell,power-sense-low" - power sense pin is low-active.
  17  - "marvell,power-control-low" - power control pin is low-active.
  18  - "marvell,no-oc-protection" - disable over-current protection.
  19  - "marvell,oc-mode-perport" - enable per-port over-current protection.
  20  - "marvell,power_on_delay" Power On to Power Good time - in ms.
  21
  22 Example:
  23
  24         usb0: ohci@4c000000 {
  25                 compatible = "marvell,pxa-ohci", "usb-ohci";
  26                 reg = <0x4c000000 0x100000>;
  27                 interrupts = <18>;
  28                 marvell,enable-port1;
  29                 marvell,port-mode = <2>; /* PMM_GLOBAL_MODE */
  30         };
  31
  32 UDC

  34 Required properties:
  35  - compatible: Should be "marvell,pxa270-udc" for USB controllers
  36    used in device mode.
  37  - reg: usb device MMIO address space
  38  - interrupts: single interrupt generated by the UDC IP
  39  - clocks: input clock of the UDC IP (see clock-bindings.txt)
  40
  41 Optional properties:
  42  - gpios:
  43    - gpio activated to control the USB D+ pullup (see gpio.txt)
