[PATCH 06/10] mmc: mxs-mmc: have dma_channel than dma_res in mxs_mmc_host

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

It replaces dma_res with dma_channel in struct mxs_mmc_host, so that
the device tree support will be a little easier, since dma channel
can not be retrieved from "struct resource *dma_res".
