The AXI MCDMA provides high-bandwidth direct memory access between memory and AXI4-Stream target peripherals. The AXI MCDMA core provides a scatter-gather interface with multiple channel support with independent configuration.

For multichannel support, refer to the AXI multichannel direct memory access IP product guide(PG228) and MCDMA driver(added in the subsequent commits). Inline with it remove axidma multichannel optional properties i.e xlnx,mcdma and dma-channels from the binding description.
