[RFC PATCH 0/2] dmaengine: xilinx_dma: Add Xilinx AXI MCDMA Engine driver support

[Radhey Shyam Pandey]

This patchset adds Xilinx AXI MCDMA IP support. The AXI MCDMA provides
high-bandwidth direct memory access between memory and AXI4-Stream target
peripherals. It supports up to 16 independent read/write channels.

MCDMA IP supports per channel interrupt output but driver support one
interrupt per channel for simplification. IP specification/programming
sequence and register description is mentioned in PG [1].


The driver is tested with xilinx internal dmatest client. In end usecase
MCDMA will be used by xilinx axiethernet driver using dma API's.
