Subject: [PATCH 0/4] dmaengine: add support mmp-pdma
Date: Fri, 27 Jul 2012 12:46:18 +0800 [thread overview]
Message-ID: <1343364382-16269-1-git-send-email-zhangfei.gao@marvell.com> (raw)
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
