+Required properties:
+- compatible :
+	- "apm,xgene-pciedma" for pcie DMA on X-Gene SoC
+- interrupts : An interrupt-specifier which is used to handle DMA interrupts
+
+Examples:
+		pciedma0 {
+			status = "disabled";
+			compatible = "apm,xgene-pciedma";
+			reg = < 0x0 0x1F2B0154 0x0 0xC

+			reg-names = "cfg", "intr";
+			interrupts = <0x0 0xC6 0x4>;
