   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 - interrupt-parent : interrupt source phandle.
  10 - fsl,fullspeed-clock : specifies the full speed USB clock source:
  11   "none": clock source is disabled
  12   "brg1" through "brg16": clock source is BRG1-BRG16, respectively
  13   "clk1" through "clk24": clock source is CLK1-CLK24, respectively
  14 - fsl,lowspeed-clock : specifies the low speed USB clock source:
  15   "none": clock source is disabled
  16   "brg1" through "brg16": clock source is BRG1-BRG16, respectively
  17   "clk1" through "clk24": clock source is CLK1-CLK24, respectively
  18 - hub-power-budget : USB power budget for the root hub, in mA.
  19 - gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP,
  20   USBRN, SPEED (optional), and POWER (optional).

  24 usb@6c0 {
  25         compatible = "fsl,mpc8360-qe-usb", "fsl,mpc8323-qe-usb";

  27         interrupts = <11>;
  28         interrupt-parent = <&qeic>;
  29         fsl,fullspeed-clock = "clk21";
  30         gpios = <&qe_pio_b  2 0 /* USBOE */
  31                  &qe_pio_b  3 0 /* USBTP */
  32                  &qe_pio_b  8 0 /* USBTN */
  33                  &qe_pio_b  9 0 /* USBRP */
  34                  &qe_pio_b 11 0 /* USBRN */
  35                  &qe_pio_e 20 0 /* SPEED */
  36                  &qe_pio_e 21 0 /* POWER */>;
