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.

Nuno Sá (4):
      dma: dma-axi-dmac: fix SW cyclic transfers
      dma: dma-axi-dmac: fix HW scatter-gather not looking at the queue
      dma: dma-axi-dmac: support bigger than 32bits addresses
      dma: dma-axi-dmac: simplify axi_dmac_parse_dt()
