-Qualcomm APQ8064 SATA PHY Controller
-------------------------------------
-
-SATA PHY nodes are defined to describe on-chip SATA Physical layer controllers.
-Each SATA PHY controller should have its own node.
-
-Required properties:
-- compatible: compatible list, contains "qcom,apq8064-sata-phy".
-- reg: offset and length of the SATA PHY register set;
-- #phy-cells: must be zero
-- clocks: a list of phandles and clock-specifier pairs, one for each entry in
-  clock-names.
-- clock-names: must be "cfg" for phy config clock.
-
-Example:
-	sata_phy: sata-phy@1b400000 {
-		compatible = "qcom,apq8064-sata-phy";
-		reg = <0x1b400000 0x200>;
-
-		clocks = <&gcc SATA_PHY_CFG_CLK>;
-		clock-names = "cfg";
-
-		#phy-cells = <0>;
-	};
