Merge tag 'dt-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC device tree updates (part 2) from Arnd Bergmann:
 "These are mostly new device tree bindings for existing drivers, as
  well as changes to the device tree source files to add support for
  those devices, and a couple of new boards, most notably Samsung's
  Exynos5 based Chromebook.

  The changes depend on earlier platform specific updates and touch the
  usual platforms: omap, exynos, tegra, mxs, mvebu and davinci."

 Required properties:
 - compatible : Should be "fsl,<chip>-dma-apbh" or "fsl,<chip>-dma-apbx"
 - reg : Should contain registers location and length
+- interrupts : Should contain the interrupt numbers of DMA channels.
+  If a channel is empty/reserved, 0 should be filled in place.
+- #dma-cells : Must be <1>.  The number cell specifies the channel ID.
+- dma-channels : Number of channels supported by the DMA controller
+
+Optional properties:
+- interrupt-names : Name of DMA channel interrupts
 
 Supported chips:
 imx23, imx28.
