Documentation/powerpc/dts-bindings/fsl/cpm_qe/qe/usb.txt

-* 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";
-	};
+Example:
+
+usb@6c0 {
+	compatible = "fsl,mpc8360-qe-usb", "fsl,mpc8323-qe-usb";
+	reg = <0x6c0 0x40 0x8b00 0x100>;
+	interrupts = <11>;
+	interrupt-parent = <&qeic>;
+	fsl,fullspeed-clock = "clk21";
+	gpios = <&qe_pio_b  2 0 /* USBOE */
+		 &qe_pio_b  3 0 /* USBTP */
+		 &qe_pio_b  8 0 /* USBTN */
+		 &qe_pio_b  9 0 /* USBRP */
+		 &qe_pio_b 11 0 /* USBRN */
+		 &qe_pio_e 20 0 /* SPEED */
+		 &qe_pio_e 21 0 /* POWER */>;

Documentation/powerpc/dts-bindings/fsl/mcu-mpc8349emitx.txt

+Freescale MPC8349E-mITX-compatible Power Management Micro Controller Unit (MCU)
+
+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@0a {
+	#gpio-cells = <2>;
+	compatible = "fsl,mc9s08qg8-mpc8349emitx",
+		     "fsl,mcu-mpc8349emitx";

Documentation/powerpc/dts-bindings/fsl/upm-nand.txt

+Freescale Localbus UPM programmed to work with NAND flash
+
+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.

+Example:
+
+upm@1,0 {
+	compatible = "fsl,upm-nand";
+	reg = <1 0 1>;
+	fsl,upm-addr-offset = <16>;

Documentation/powerpc/dts-bindings/gpio/led.txt

+LED connected to GPIO
+
+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.
