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 only change is the addition of the DMA_PREP_LOAD_EOT transaction flag (and the corresponding DMA_LOAD_EOT capability bit), as requested during the review of v4. Please see the discussions from v4 for the rationale. The driver has been successfully tested with the ZynqMP DisplayPort subsystem DRM driver.
