Subject: [PATCH mmc-next 0/3] solve SDHCI DWC MSHC 128MB DMA boundary
 limitation
Message-ID: <20180725174235.1ca764cf@xhacker.debian>

When using DMA, if the DMA addr spans 128MB boundary, we have to split
the DMA transfer into two so that each one doesn't exceed the boundary.

patch1 adds adma_table_num to struct sdhci_host so that driver can
control the ADMA table number.
patch2 introduces adma_write_desc() hook to struct sdhci_ops so that
driver can override it.
patch3 finally solves the 128MB boundary limitation.
