-Synopsys DesignWare AXI DMA Controller
-
-Required properties:
-- compatible: "snps,axi-dma-1.01a"
-- reg: Address range of the DMAC registers. This should include
-  all of the per-channel registers.
-- interrupt: Should contain the DMAC interrupt number.
-- dma-channels: Number of channels supported by hardware.
-- snps,dma-masters: Number of AXI masters supported by the hardware.
-- snps,data-width: Maximum AXI data width supported by hardware.
-  (0 - 8bits, 1 - 16bits, 2 - 32bits, ..., 6 - 512bits)
-- snps,priority: Priority of channel. Array size is equal to the number of
-  dma-channels. Priority value must be programmed within [0:dma-channels-1]
-  range. (0 - minimum priority)
-- snps,block-size: Maximum block size supported by the controller channel.
-  Array size is equal to the number of dma-channels.
-
-Optional properties:
-- snps,axi-max-burst-len: Restrict master AXI burst length by value specified
-  in this property. If this property is missing the maximum AXI burst length
-  supported by DMAC is used. [1:256]
-
-Example:
-
-dmac: dma-controller@80000 {
-	compatible = "snps,axi-dma-1.01a";
-	reg = <0x80000 0x400>;
-	clocks = <&core_clk>, <&cfgr_clk>;

-	snps,data-width = <3>;
