[PATCH 0/3] riscv: sophgo: allow DMA multiplexer set channel number for DMA controller

[Inochi Amaoto]

As the DMA controller on Sophgo CV1800 series SoC only has 8 channels,
the SoC provides a dma multiplexer to reuse the DMA channel. However,
the dma multiplexer also controlls the DMA interrupt multiplexer, which
means that the dma multiplexer needs to know the channel number.

Inochi Amaoto (3):
  dt-bindings: dma: snps,dw-axi-dmac: Add CV1800B compatible
  dmaengine: dw-axi-dmac: Add support for CV1800B DMA
  riscv: dts: sophgo: cv180x: Allow the DMA multiplexer to set channel
    number for DMA controller
