Hi everyone, I am working on a SOC which it's RAM starts at 0x200M. For some reason I need to limit the DMA allocations up to 0x220M, so I called - dma_set_mask_and_coherent(mmc_dev(mmc), 0x21FFFFFFF). I noticed that dev->dma_mask was not set, while dev->coherent_dma_mask was set. Still, calling dma_alloc_coherent returns buffers above the requested limit. How can I limit the buffer address?
