Merge tag 'imx-dt-3.9' of git://git.linaro.org/people/shawnguo/linux-2.6 into late/dt
From Shawn Guo: imx device tree changes for 3.9 - Some tweaking and updates on device tree sources - Enable imx6q-cpufreq support for device tree boot - IMX/MXC onewire driver device tree conversion.

+* Freescale i.MX One wire bus master controller
+
+Required properties:
+- compatible : should be "fsl,imx21-owire"
+- reg : Address and length of the register set for the device
+
+Optional properties:
+- clocks : phandle of clock that supplies the module (required if platform
+ clock bindings use device tree)
+
+Example:
+
+- From imx53.dtsi:
