Kind regards Uffe
To improve performance, add pre_req and post_req support into renesas_internal_dmac. Note that the patch [1/2] is a bug fix patch. Changes from v1: - Add a bug fix patch for hardware limitation in patch 1. - Remove a redundant argument in the unmap function in patch 2. - Describe the reason why we should not use host->sg_ptr in patch 2. - Rename argument of struct mmc_request from req to mrq in patch 2.
