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.
