Required properties:
- compatible: "snps,dma-spear1340"
- reg: Address range of the DMAC registers
- interrupt-parent: Should be the phandle for the interrupt controller
  that services interrupts for this device
- interrupt: Should contain the DMAC interrupt number

Example:

	dma@fc000000 {
		compatible = "snps,dma-spear1340";
		reg = <0xfc000000 0x1000>;
		interrupt-parent = <&vic1>;
		interrupts = <12>;
	};
