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 v2->v3 (suggested by Andy Shevchenko and Vinod Koul): * Fix SPDX licence comment style. * Use KBUILD_MODNAME macro instead of custom one. * Refactor dma_chan_tx_status function. * Refactor dma_chan_pause function. * Remove dma_cookie_init() call from dma_chan_alloc_chan_resources() * Use upper_32_bits() and lower_32_bits() instead of custom one. * Add __maybe_unused to runtime PM callback functions instead of CONFIG_PM ifdef use. * Other small fixies.
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.
