[PATCH v5 3/3] mmc: sdhci-of-dwcmshc: solve 128MB DMA boundary limitation

2018-08-27 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. Signed-off-by: Jisheng Zhang --- drivers/mmc/host/sdhci-of-dwcmshc.c | 41 + 1 file changed, 41 insertions(+) diff --git a/d
