+* 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 {
