Hi all,
Here are the notorious bindings. I believe I addressed Segher's comments.
Major changes are in the LEDs bindings, I removed all the cruft and now
using "aliases" mechanism to determine LEDs' trigger.
Comments, suggestions?
Thanks,

+ Required properties:
+ - 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:

+ "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+ "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+ - hub-power-budget : optional, USB power budget for the root hub, in mA.
+ - gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP,

+ - compatible : "fsl,<mcu-chip>-<board>", "fsl,mcu-mpc8349emitx";
+ - reg : should specify I2C address (0x0a).
+ - #gpio-cells : should be 2.
+ - gpio-controller : should be present;
+
+ Example:
