30 Client drivers (device nodes requiring dma transfers from dev-to-mem or
31 mem-to-dev) should specify the DMA channel numbers and dma channel names
34   [property name]  = <[phandle of the dma controller] [dma request id]>;
35   [property name]  = <[dma channel name]>
37       where 'dma request id' is the dma request number which is connected
38       to the client controller. The 'property name' 'dmas' and 'dma-names'
39       as required by the generic dma device tree binding helpers. The dma
40       names correspond 1:1 with the dma request ids in the dmas property.
