[PATCH mmc-next v3 0/3] solve SDHCI DWC MSHC 128MB DMA boundary limitation

2018-07-29 Thread Jisheng Zhang
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_
