[RFC PATCH v5 0/9] Add external dma support for Synopsys MSHC

2015-08-14 Thread Shawn Lin
Synopsys DesignWare mobile storage host controller supports three types of transfer mode: pio, internal dma and external dma. However, dw_mmc can only supports pio and internal dma now. Thus some platforms using dw-mshc integrated with generic dma can't work in dma mode. So we submit this patch
