-* USB (Universal Serial Bus Controller)
+Freescale QUICC Engine USB Controller
 
 Required properties:
-- compatible : could be "qe_udc" or "fhci-hcd".
-- mode : the could be "host" or "slave".
-- reg : Offset and length of the register set for the device
-- interrupts : <a b> where a is the interrupt number and b is a
-  field that represents an encoding of the sense and level
-  information for the interrupt.  This should be encoded based on
-  the information in section 2) depending on the type of interrupt
-  controller you have.
-- interrupt-parent : the phandle for the interrupt controller that
-  services interrupts for this device.
+- compatible : should be "fsl,<chip>-qe-usb", "fsl,mpc8323-qe-usb".
+- reg : the first two cells should contain usb registers location and
+  length, the next two two cells should contain PRAM location and
+  length.
+- interrupts : should contain USB interrupt.
+- interrupt-parent : interrupt source phandle.
+- fsl,fullspeed-clock : specifies the full speed USB clock source:
+  "none": clock source is disabled
+  "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+  "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+- fsl,lowspeed-clock : specifies the low speed USB clock source:
+  "none": clock source is disabled
+  "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+  "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+- hub-power-budget : USB power budget for the root hub, in mA.
+- gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP,
+  USBRN, SPEED (optional), and POWER (optional).
 
-Example(slave):
-        usb@6c0 {
-                compatible = "qe_udc";
-                reg = <6c0 40>;
-                interrupts = <8b 0>;
-                interrupt-parent = <700>;
-                mode = "slave";
-        };
