-Xilinx AXI CDMA engine, it does transfers between memory-mapped source
-address and a memory-mapped destination address.
-
-Required properties:
-- compatible           : Should be "xlnx,axi-cdma-1.00.a"
-- #dma-cells           : Should be <1>, see "dmas" property below
-- reg                  : Should contain cdma registers location and length.
-- dma-channel child node: Should have only one channel
-
-Optional properties:
-- xlnx,include-sg      : Tells whether configured for Scatter-mode in
-                         the hardware.
-
-Required child node properties:
-- interrupts           : Should contain per channel CDMA interrupts.
-- xlnx,datawidth       : Should contain the stream data width, take values
-                         {32,64...1024}.
-
-Option child node properties:
-- xlnx,has-dre         : Tells whether hardware is configured for Data
-                         Realignment Engine.

-Example:

-axi_cdma_0: axicdma@7e200000 {
-       compatible = "xlnx,axi-cdma-1.00.a";
-       #dma-cells = <1>;

-* DMA client

-Required properties:
-- dmas         : a list of <[Central DMA device phandle] [Channel ID]> pairs,
-                 where Channel ID is '0' for write/tx and '1' for read/rx
-                  channel.
-- dma-names    : a list of DMA channel names, one per "dmas" entry

-Example:

-cdmatest_0: cdmatest@0 {
-       compatible ="xlnx,axi-cdma-test-1.00.a";
-       dmas = <&axi_cdma_0 0>;
