+Hisilicon hix5hd2 SATA PHY
+-----------------------
+
+Required properties:
+- compatible: should be "hisilicon,hix5hd2-sata-phy"
+- reg: offset and length of the PHY registers
+- #phy-cells: must be 0
+Refer to phy/phy-bindings.txt for the generic PHY binding properties
+
+Optional Properties:
+- hisilicon,peripheral-syscon: phandle of syscon used to control peripheral.
+- hisilicon,power-reg: offset and bit number within peripheral-syscon,
+        register of controlling sata power supply.
+
+Example:
+        sata_phy: phy@f9900000 {
+                compatible = "hisilicon,hix5hd2-sata-phy";
+                reg = <0xf9900000 0x10000>;
+                #phy-cells = <0>;
+                hisilicon,peripheral-syscon = <&peripheral_ctrl>;
+                hisilicon,power-reg = <0x8 10>;
+        };
