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

+
+    Required properties:
+      - compatible : should be "fsl,<chip>-qe-usb", "fsl,mpc8323-qe-usb";
+      - reg : the first two cells should contain gtm 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 in
+        "clk<num>" or "brg<num>" format.
+      - fsl,lowspeed-clock : specifies the low speed USB clock source in
+        "clk<num>" or "brg<num>" format.
+      - fsl,usb-mode : should be "host".
+      - linux,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@6c0 {
+		compatible = "fsl,mpc8360-qe-usb", "fsl,mpc8323-qe-usb";
+		reg = <0x6c0 0x40 0x8b00 0x100>;

+
+    Required properties:
+      - compatible : should be "linux,gpio-led".
+      - linux,name : LED name.
+      - linux,active-low : property should be present if LED wired as
+        active-low.
+      - linux,default-trigger : Linux default trigger for this LED.
+      - linux,brightness : default brightness.
+      - gpios : should specify LED GPIO.
+
+    Example:
+
+	led@0 {
+		compatible = "linux,gpio-led";

+		linux,brightness = <1>;
+		linux,active-low;

+		#gpio-cells = <2>;
+		compatible = "fsl,mc9s08qg8-mpc8349emitx",

+		reg = <0x0a>;
+		gpio-controller;

+
+    x) Freescale Localbus UPM programmed to work with NAND flash
+
+      Required properties:
+      - #address-cells : should be 0;
+      - #size-cells : should be 0;
+      - 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.
+
+      Example:
+
+	upm@1,0 {
+		#address-cells = <0>;
+		#size-cells = <0>;
+		compatible = "fsl,upm-nand";
+		reg = <1 0 1>;
+		fsl,upm-addr-offset = <16>;
+		fsl,upm-cmd-offset = <8>;
+		gpios = <&qe_pio_e 18 0>;
+
+		flash {
+			#address-cells = <1>;
+			#size-cells = <1>;
+			compatible = "stmicro,NAND512W3A2BN6E";
+
+			partition@0 {
+				...
+			};
+		};
+	};
Where can I find the code for that binding? fsl_upm_nand.c from
http://patchwork.ozlabs.org/linuxppc/patch?q=upm&id=17306 does not parse
OF partitions. Are there any plans to push the fsl_upm_nand driver
upstream? I'm currently implementing NAND support for the TQM8548 and
want to base it on common code.

Thanks,

Wolfgang.
