    1 Freescale SOC USB controllers
    2 
    3 The device node for a USB controller that is part of a Freescale
    4 SOC is as described in the document "Open Firmware Recommended
    5 Practice : Universal Serial Bus" with the following modifications
    6 and additions :
    7 
    8 Required properties :
    9  - compatible : Should be "fsl-usb2-mph" for multi port host USB
   10    controllers, or "fsl-usb2-dr" for dual role USB controllers
   11    or "fsl,mpc5121-usb2-dr" for dual role USB controllers of MPC5121.
   12    Wherever applicable, the IP version of the USB controller should
   13    also be mentioned (for eg. fsl-usb2-dr-v2.2 for bsc9132).
   14  - phy_type : For multi port host USB controllers, should be one of
   15    "ulpi", or "serial". For dual role USB controllers, should be
   16    one of "ulpi", "utmi", "utmi_wide", or "serial".
   17  - reg : Offset and length of the register set for the device
   18  - port0 : boolean; if defined, indicates port0 is connected for
   19    fsl-usb2-mph compatible controllers.  Either this property or
   20    "port1" (or both) must be defined for "fsl-usb2-mph" compatible
   21    controllers.
   22  - port1 : boolean; if defined, indicates port1 is connected for
   23    fsl-usb2-mph compatible controllers.  Either this property or
   24    "port0" (or both) must be defined for "fsl-usb2-mph" compatible
   25    controllers.
   26  - dr_mode : indicates the working mode for "fsl-usb2-dr" compatible
   27    controllers.  Can be "host", "peripheral", or "otg".  Default to
   28    "host" if not defined for backward compatibility.
   29 
   30 Recommended properties :
   31  - interrupts : <a b> where a is the interrupt number and b is a
   32    field that represents an encoding of the sense and level
   33    information for the interrupt.  This should be encoded based on
   34    the information in section 2) depending on the type of interrupt
   35    controller you have.
   36 
   37 Optional properties :
   38  - fsl,invert-drvvbus : boolean; for MPC5121 USB0 only. Indicates the
   39    port power polarity of internal PHY signal DRVVBUS is inverted.
   40  - fsl,invert-pwr-fault : boolean; for MPC5121 USB0 only. Indicates
   41    the PWR_FAULT signal polarity is inverted.
   42 
   43 Example multi port host USB controller device node :
   44         usb@22000 {
   45                 compatible = "fsl-usb2-mph";
   46                 reg = <22000 1000>;
   47                 #address-cells = <1>;
   48                 #size-cells = <0>;
   49                 interrupt-parent = <700>;
   50                 interrupts = <27 1>;
   51                 phy_type = "ulpi";
   52                 port0;
   53                 port1;
   54         };
   55 
   56 Example dual role USB controller device node :
   57         usb@23000 {
   58                 compatible = "fsl-usb2-dr";
   59                 reg = <23000 1000>;
   60                 #address-cells = <1>;
   61                 #size-cells = <0>;
   62                 interrupt-parent = <700>;
   63                 interrupts = <26 1>;
   64                 dr_mode = "otg";
   65                 phy = "ulpi";
   66         };
   67 
   68 Example dual role USB controller device node for MPC5121ADS:
   69 
   70         usb@4000 {
   71                 compatible = "fsl,mpc5121-usb2-dr";
   72                 reg = <0x4000 0x1000>;
   73                 #address-cells = <1>;
   74                 #size-cells = <0>;
   75                 interrupt-parent = < &ipic >;
   76                 interrupts = <44 0x8>;
   77                 dr_mode = "otg";
   78                 phy_type = "utmi_wide";
   79                 fsl,invert-drvvbus;
   80                 fsl,invert-pwr-fault;
   81         };
