dt-bindings: dmaengine: xilinx_dma: Remove axidma multichannel support (96336cc0) · Commits · 戴 / test

The AXI DMA multichannel support is deprecated in the IP and it is no longer actively supported. 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. Signed-off-by:
