-- reg: base address and length of the registers block for the DMAC
-- interrupts: interrupt specifiers for the DMAC, one for each entry in
- interrupt-names.
-- interrupt-names: one entry per channel, named "ch%u", where %u is the
- channel number ranging from zero to the number of channels minus one.
-- clocks: a list of phandle + clock-specifier pairs.
-- #dma-cells: must be <1>, the cell specifies the channel number of the DMAC
- port connected to the DMA client.
-- dma-channels: number of DMA channels
