+* Marvell Berlin SATA nodes
+
+Required properties:
+- compatible: "marvell,berlin-ahci"
+- interrupts: interrupt mapping for the SATA IRQ
+- reg: address and length of the register
+- phys: references to the SATA PHY nodes
+- phy-names: should be "port0" or/and "port1"
+
+Example:
+	ahci: sata at f7e90000 {
+		compatible = "marvell,berlin-ahci";
+		reg = <0xf7e90000 0x1000>;
+		interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
+		phys = <&sata_phy 0>, <&sata_phy 1>;
+		phy-names = "port0", "port1";
+		status = "okay";
+	};
