This patch adds few bindings for the new drivers to be submitted through
the appropriate maintainers.

Segher, thanks for the comments on the previous version. Do you see any
issues with this one or anything I could improve further?

And if there are no issues... Kumar, could you apply this for powerpc-next?

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

+        "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,
+        USBRN, SPEED (optional), and POWER (optional).
+
+    Example:
+
+	usb at 6c0 {
+		compatible = "fsl,mpc8360-qe-usb", "fsl,mpc8323-qe-usb";
+		reg = <0x6c0 0x40 0x8b00 0x100>;

+			 &qe_pio_b 11 0 /* USBRN */
+			 &qe_pio_e 20 0 /* SPEED */
+			 &qe_pio_e 21 0 /* POWER */>;

+
+    w) Freescale MCU with MPC8349E-mITX compatible firmware
+
+    Required properties:
+      - 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:
+
+	mcu_pio: mcu at 0a {

+
+      Required properties:
+      - compatible : "fsl,upm-nand".
+      - reg : should specify localbus chip select and size used for the chip.
+      - fsl,upm-addr-offset : UPM pattern offset for the address latch.
+      - fsl,upm-cmd-offset : UPM pattern offset for the command latch.
+      - gpios : may specify optional GPIO connected to the Ready-Not-Busy pin.

+
+    Required properties:
+      - compatible : should be "gpio-led".
+      - label : (optional) the label for this LED. If omitted, the label is
+        taken from the node name (excluding the unit address).
+      - gpios : should specify LED GPIO.
+
+    Example:
+
+	led at 0 {
+		compatible = "gpio-led";
+		label = "hdd";
+		gpios = <&mcu_pio 0 1>;
