Hi Vinod, Dan, Scott and Leo, please have a look at these V2 patches.

Freescale QorIQ T4 and B4 introduce new 8-channel DMA engines, this patch set
adds support this DMA engine.

V3->V4 changes:
- introduce new patch [1/3] to revise the legacy dma binding document
- and then add new paragraph to describe new dt node binding in [2/3]
- rebase to latest kernel v3.11-rc1

V2->V3 changes:
- edit Documentation/devicetree/bindings/powerpc/fsl/dma.txt
- edit text string in Kconfig and the driver files, using "elo series" to
  mention all the current "elo*"

V1->V2 changes:
- removed the codes handling the register dgsr1, since it isn't used corrently
- renamed the DMA DT compatible to "fsl,elo3-dma"
- renamed the new dts files to "elo3-dma-<n>.dtsi"
