This two patches add the dma memory copy and PM suspend/resume support
for the Freescale eDMA engine.
Jingchang Lu (2):
dmaengine: fsl-edma: add dma memcpy support
dmaengine: fsl-edma: add PM suspend/resume support
This adds the memory copy capability support, the memcpy
functionality needs to configure the DMAMUX of the channel
with the always on slave id.

If a device doesn't have clk property, then info->clk may

This series add Freescale eDMA engine support.
Jingchang Lu (3):
ARM: imx: Add DMAMUX clock for Vybrid vf610 SoC
ARM: dts: vf610: Add eDMA node
dma: Add Freescale eDMA engine driver support

Add Freescale enhanced direct memory(eDMA) controller support.
The eDMA controller deploys DMAMUXs routing DMA request sources(slot)
to eDMA channels.
This module can be found on Vybrid and LS-1 SoCs.
