[PATCH 5/5] dmaengine: dw: Add DMA-channels mask cell support

2020-07-30 Thread Serge Semin
DW DMA IP-core provides a way to synthesize the DMA controller with channels having different parameters like maximum burst-length, multi-block support, maximum data width, etc. Those parameters both explicitly and implicitly affect the channels performance. Since DMA slave devices might be very
