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 most notable change is the replacement of the proposed new DMA transfer type that combined interleaved and cyclic tranfers with a new dma_ctrl_flags (patch 3/6, suggested by Peter). The driver has been successfully tested with the ZynqMP DisplayPort subsystem DRM driver.
