1 * ARM PrimeCell PL330 DMA Controller
3 The ARM PrimeCell PL330 DMA controller can move blocks of memory contents
13   - dma-coherent      : Present if dma operations are coherent
14   - #dma-cells: must be <1>. used to represent the number of integer
16   - dma-channels: contains the total number of DMA channels supported by the DMAC
17   - dma-requests: contains the total number of DMA requests supported by the DMAC
22   - reset-names: must contain at least "dma", and optional is "dma-ocp".
30 		#dma-cells = <1>;
31 		#dma-channels = <8>;
32 		#dma-requests = <32>;
35 Client drivers (device nodes requiring dma transfers from dev-to-mem or
36 mem-to-dev) should specify the DMA channel numbers and dma channel names
39   [property name]  = <[phandle of the dma controller] [dma request id]>;
40   [property name]  = <[dma channel name]>
42       where 'dma request id' is the dma request number which is connected
43       to the client controller. The 'property name' 'dmas' and 'dma-names'
44       as required by the generic dma device tree binding helpers. The dma
45       names correspond 1:1 with the dma request ids in the dmas property.
49 	    dma-names = "tx", "rx";
