Merge branch 'imx/dt-for-3.6' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/dt

From Shawn Guo <shawn.guo@linaro.org>:

Here is the second (last) batch of imx device tree changes for 3.6.

* 'imx/dt-for-3.6' of git://git.linaro.org/people/shawnguo/linux-2.6:
  ARM: imx6q: ensure ANATOP controller is available
  ARM: dts: imx6q-sabrelite: add ecspi1 pinctrl support
  ARM: dts: imx6q-sabrelite: add usb devices
  ARM: imx6q: disable usb charger detector
  ARM: imx6q: add usbphy clocks
  ARM: imx6q: add usb controller clock lookups
  ARM: dts: imx: update #interrupt-cells for gpio nodes
  bindings: update imx and mxs #gpio-cells
