+* Synopsys Designware DMA Controller
+
+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>;
+ };
