Subject: [PATCH RESEND 0/4] dma: dma-axi-dmac: fixes and improvements





This series adds some fixes to the DMA core with respect with cyclic

transfer and HW scatter gather.



It also adds some improvements. Most notably for allowing bigger that

32bits DMA masks so we do not have to rely on bounce buffers from

swiotlb.
