I have listed Sergei as the maintainer, as he wrote the original driver
and bindings.  Sergei: Please scream if this is inappropriate ;-)

-* Renesas R-Car generation 3 PCIe PHY
-
-This file provides information on what the device node for the R-Car
-generation 3 PCIe PHY contains.
-
-Required properties:
-- compatible: "renesas,r8a77980-pcie-phy" if the device is a part of the
-	      R8A77980 SoC.
-- reg: offset and length of the register block.
-- clocks: clock phandle and specifier pair.
-- power-domains: power domain phandle and specifier pair.
-- resets: reset phandle and specifier pair.
-- #phy-cells: see phy-bindings.txt in the same directory, must be <0>.
-
-Example (R-Car V3H):
-
-	pcie-phy@e65d0000 {
-		compatible = "renesas,r8a77980-pcie-phy";
-		reg = <0 0xe65d0000 0 0x8000>;
-		#phy-cells = <0>;
-		clocks = <&cpg CPG_MOD 319>;
-		power-domains = <&sysc 32>;
-		resets = <&cpg 319>;
-	};
