[PATCH V4 1/3] mmc: sdhci: add support for using external DMA devices

2018-12-11 Thread Chunyan Zhang
Some standard SD host controllers can support both external dma controllers as well as ADMA/SDMA in which the SD host controller acts as DMA master. TI's omap controller is the case as an example. Currently the generic SDHCI code supports ADMA/SDMA integrated in the host controller but does not
