Hi Vinod, Dan, Scott and Leo, please have a look at these V7 patches.

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

V6->V7 changes:
- only remove unnecessary "CHIP-dma" explanations in [1/3]

V5->V6 changes:
- minor updates of descriptions in binding document and Kconfig
- remove [4/4], that should be another patch in future

V4->V5 changes:
- update description in the dt binding document, to make it more resonable
- add new patch [4/4] to eliminate a compiling warning which already exists
for a long time

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 currently
- renamed the DMA DT compatible to "fsl,elo3-dma"
- renamed the new dts files to "elo3-dma-<n>.dtsi"
