Hello, This patch series adds a new driver for the DPDMA engine found in the Xilinx ZynqMP. The previous version can be found at [1]. All review comments have been taken into account. The main change is the addition of documentation. The driver has been successfully tested with the ZynqMP DisplayPort subsystem DRM driver. As I would like to merge both this series and the DRM driver that depends on it for v5.9, I have based those patches on top of v5.8-rc1 and pushed a tag to git://linuxtv.org/pinchartl/media.git dma-zynqmp-20200708-base to be merged in both the dmaengine and DRM tree (Daniel and Dave on CC). There's unfortunately a conflict with the DMA engine next branch, which I have resolved and pushed to git://linuxtv.org/pinchartl/media.git dma-zynqmp-20200708-resolved The first tag would thus be merged in the DRM tree, while the second tag would be merged in the DMA engine tree (unless Vinod would prefer merging the first tag and resolving the conflict himself). Vinod, could you please confirm that this is OK with you ? I'll create new signed tags with your Acked-by/Reviewed-by tags once you finish reviewing the series (unless you prefer applying the patches yourself and provide a base branch on top of v5.8-rc1 as I've done).
