Merge branch 'imx/dt/for-3.5' of git://git.linaro.org/people/shawnguo/linux-2.6.git into next/dt2

Shawn Guo <[email protected]> writes:

  I chose to base it on Sascha's imx-common-clk series than -rc, because
  otherwise it will keep patching clock file that has been removed by
  imx-common-clk series.  It also depends on imx-pinctrl pull-request
  I just sent to be functional.

  Note: when imx-common-clk and imx-pinctrl get merged together, the
  following files will have conflicts.  But the conflicts should not be
  so hard to resolve.

[arnd: resolved those merge conflicts by pulling pinctrl branch]

* imx/dt: (24 commits)
  ARM: dts: imx53-qsb: enable audio support
