Subject: [RFC v2 0/4] dmaengine: sf-pdma: Add platform dma driver
Date: Mon, 14 Oct 2019 15:54:23 +0800 [thread overview]
Message-ID: <20191014075502.15105-1-green.wan@sifive.com> (raw)
Add PDMA driver support for SiFive HiFive Unleashed RevA00 board. Mainly follows
DMAengine controller doc[1] to implement and take other DMA drivers as reference.
Such as
- drivers/dma/fsl-edma.c
- drivers/dma/dw-edma/
- drivers/dma/pxa-dma.c
Using DMA test client[2] to test. Detailed datasheet is doc[3]. Driver supports:
- 4 physical DMA channels, share same DONE and error interrupt handler.
- Support MEM_TO_MEM
- Tested by DMA test client
- patches include DT Bindgins document and dts for fu450-c000 SoC. Separate dts
patch for easier review and apply to different branch or SoC platform.
- retry 1 time if DMA error occurs.
