dw_dmac: allocate dma descriptors from DMA_COHERENT memory Currently descriptors are allocated from normal cacheable memory and that slows down filling the descriptors, as we need to call cache_coherency routines afterwards. It would be better to allocate memory for these descriptors from DMA_COHERENT memory. This would make code much cleaner too.
