-Cadence DPHY
-============
-
-Cadence DPHY block.
-
-Required properties:
-- compatible: should be set to "cdns,dphy".
-- reg: physical base address and length of the DPHY registers.
-- clocks: DPHY reference clocks.
-- clock-names: must contain "psm" and "pll_ref".
-- #phy-cells: must be set to 0.
-
-Example:
-	dphy0: dphy@fd0e0000{
-		compatible = "cdns,dphy";
-		reg = <0x0 0xfd0e0000 0x0 0x1000>;
-		clocks = <&psm_clk>, <&pll_ref_clk>;
-		clock-names = "psm", "pll_ref";
-		#phy-cells = <0>;
-	};
