This patch series add support for the DW AXI DMAC controller. DW AXI DMAC is a part of HSDK development board from Synopsys. In this driver implementation only DMA_MEMCPY transfers are supported.

Changes v1->v2 (suggested by Andy Shevchenko): * Use SPDX licence identifier. * Refactor axi_chan_get_xfer_width function. * Fix timeout calculation in dma_chan_pause. * Add record to MAINTAINERS in correct alphabetical order.
