1Freescale QUICC Engine USB Controller
2
3Required 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).
