Kedareswara rao Appana	e598e6eb46	dmaengine: xilinx: Fix race condition in axi dma cyclic dma mode ... In cyclic DMA mode need to link the tail bd segment with the head bd segment to process bd's in cyclic. Current driver is doing this only for tx channel needs to update the same for rx channel case also. This patch fixes the same.

Kedareswara rao Appana	e131f1ba6f	dmaengine: xilinx: Use different channel names for each dma ... Current driver assumes that child node channel name is either "xlnx,axi-vdma-mm2s-channel" or "xlnx,axi-vdma-s2mm-channel" which is confusing the users of AXI DMA and CDMA. This patch fixes this issue by using different channel names for the AXI DMA and AXI CDMA child nodes.

Kedareswara rao Appana	fde57a7c44	dmaengine: xilinx: Rename driver and config ... In the existing vdma driver support for AXI DMA and CDMA got added so the driver is no longer VDMA specific. This patch renames the driver and DT binding doc to xilinx_dma and updates the Kconfig description for all the DMAS.
