    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
   33 
   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)
   44 
   45 Example:
   46 
   47                 pxa27x_udc: udc@40600000 {
   48                         compatible = "marvell,pxa270-udc";
   49                         reg = <0x40600000 0x10000>;
   50                         interrupts = <11>;
   51                         clocks = <&pxa2xx_clks 11>;
   52                         gpios = <&gpio 22 GPIO_ACTIVE_LOW>;
   53                 };
