+Berlin SATA PHY
+---------------
+
+Required properties:
+- compatible: should be "marvell,berlin2q-sata-phy"
+- address-cells: should be 1
+- size-cells: should be 0
+- phy-cells: from the generic PHY bindings, must be 1
+- reg: address and length of the register
+- clocks: reference to the clock entry
+
+Sub-nodes:
+Each PHY should be represented as a sub-node.
+
+Sub-nodes required properties:
+- reg: the PHY number
+
+Example:
+ sata_phy: phy@f7e900a0 {
+ compatible = "marvell,berlin2q-sata-phy";
+ reg = <0xf7e900a0 0x200>;
+ clocks = <&chip CLKID_SATA>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ #phy-cells = <1>;
+
+ sata-phy@0 {
+ reg = <0>;
+ };
+
+ sata-phy@1 {
+ reg = <1>;
+ };
+ };
