Merge tag 'mxs-dt-3.10' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/dt2

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

The mxs device tree changes for 3.10:

* Move enet_out clk into device tree and have fec driver handle it.
* Convert mxsfb driver to generic display timings bindings, and remove
  the mxsfb auxdata from platform code.
* Add generic DMA device tree binding for mxs-dma, and convert the most
  of client device drivers to it.
* Change mxsfb driver to use regulator for controlling power of panel.
* A few device tree source updates

* tag 'mxs-dt-3.10' of git://git.linaro.org/people/shawnguo/linux-2.6: (23 commits)
