[PATCH 0/4] dmaengine: add support mmp-pdma

[Zhangfei Gao <zhangfei.gao@xxxxxxxxxxx>]

v0->v1
Update dt member and desc according to Arnd's suggestion
Use dma_slave_config.slave_id to transfer drcmr followed Vinod's suggestion

Patch 4 is upload as example
mtd: pxa3xx-nand: replace pxa_request_dma with dmaengine
We would like hold this patch currently
since pdma will grab irq and disable pxa_init_dma. 

Any attempt of replacing pxa_request_dma with dmaengine on pxa3xx platform are welcome
Here are many replacing and verifying work to do.


mmp-pdma is added under dmaengine framework.
The final purpose is replacing arch/arm/plat-pxa/dma.c

Test on pxa910 with pxa3xx-nand and dmatest.ko

Zhangfei Gao (4):
  dmaengine: mmp-pdma support
  dmaengine: mmp_tdma: add dt support
  dmatest: add dmaengine_slave_config for DMA_MEMCPY
  mtd: pxa3xx-nand: replace pxa_request_dma with dmaengine
