    1 Freescale QUICC Engine USB Controller
    2 
    3 Required properties:
    4 - compatible : should be "fsl,<chip>-qe-usb", "fsl,mpc8323-qe-usb".
    5 - reg : the first two cells should contain usb registers location and
    6   length, the next two two cells should contain PRAM location and
    7   length.
    8 - interrupts : should contain USB interrupt.
    9 - fsl,fullspeed-clock : specifies the full speed USB clock source:
   10   "none": clock source is disabled
   11   "brg1" through "brg16": clock source is BRG1-BRG16, respectively
   12   "clk1" through "clk24": clock source is CLK1-CLK24, respectively
   13 - fsl,lowspeed-clock : specifies the low speed USB clock source:
   14   "none": clock source is disabled
   15   "brg1" through "brg16": clock source is BRG1-BRG16, respectively
   16   "clk1" through "clk24": clock source is CLK1-CLK24, respectively
   17 - hub-power-budget : USB power budget for the root hub, in mA.
   18 - gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP,
   19   USBRN, SPEED (optional), and POWER (optional).

   21 Example:
   22 
   23 usb@6c0 {
   24         compatible = "fsl,mpc8360-qe-usb", "fsl,mpc8323-qe-usb";
   25         reg = <0x6c0 0x40 0x8b00 0x100>;
   26         interrupts = <11>;
   27         interrupt-parent = <&qeic>;
   28         fsl,fullspeed-clock = "clk21";
   29         gpios = <&qe_pio_b  2 0 /* USBOE */
   30                  &qe_pio_b  3 0 /* USBTP */
   31                  &qe_pio_b  8 0 /* USBTN */
   32                  &qe_pio_b  9 0 /* USBRP */
   33                  &qe_pio_b 11 0 /* USBRN */
   34                  &qe_pio_e 20 0 /* SPEED */
   35                  &qe_pio_e 21 0 /* POWER */>;
   36 };
