Some background about the patch series: Xilinx Axi Ethernet device driver (xilinx_axienet_main.c) currently has axi-dma code inside it. The goal is to refactor axiethernet driver and use existing AXI DMA driver using DMAEngine API. This patchset does feature addition and optimization to support axidma integration with axiethernet network driver. Once axidma version is accepted mcdma specific changes will be added in followup version. This series is based on dmaengine tree commit: #a38fd8748464 Changes for v2: - Use metadata API[1] for passing metadata from dma to netdev client. - Read irq-delay from DT. - Remove desc_callback_valid check. - Addressed RFC v1 comments[2]. - Minor code refactoring. Comments, suggestions are very welcome!
