Merge tag 'dt-for-3.7' of git://sources.calxeda.com/kernel/linux

Pull devicetree updates from Rob Herring:
 - Import of latest upstream device tree compiler (dtc)
 - New function of_get_child_by_name
 - Support for #size-cells of 0 and #addr-cells of >2
 - Couple of DT binding documentation updates

Fix up trivial conflicts due to of_get_child_by_name() having been added
next to the new of_get_next_available_child().

+* Freescale i.MX UART controller
+
+Required properties:
+- compatible : should be "fsl,imx21-uart"
+- reg : Address and length of the register set for the device
+- interrupts : Should contain UART interrupt number
+
+Optional properties:
+- fsl,uart-has-rtscts: indicate that RTS/CTS signals are used
+
+Note: Each uart controller should have an alias correctly numbered
+in "aliases" node.
+
+Example:
+
+- From imx51.dtsi:
+aliases {
+	serial0 = &uart1;
+	serial1 = &uart2;
+	serial2 = &uart3;
+};
+
+uart1: serial@73fbc000 {
+	compatible = "fsl,imx51-uart", "fsl,imx21-uart";
+	reg = <0x73fbc000 0x4000>;
+	interrupts = <31>;
+	status = "disabled";
+}
+
+- From imx51-babbage.dts:
+uart1: serial@73fbc000 {
+	fsl,uart-has-rtscts;
+	status = "okay";
+};
