1* Renesas R-Car generation 3 PCIe PHY
2
3This file provides information on what the device node for the R-Car
4generation 3 PCIe PHY contains.
5
6Required properties:
7- compatible: "renesas,r8a77980-pcie-phy" if the device is a part of the
8	      R8A77980 SoC.
9- reg: offset and length of the register block.
10- clocks: clock phandle and specifier pair.
11- power-domains: power domain phandle and specifier pair.
12- resets: reset phandle and specifier pair.
13- #phy-cells: see phy-bindings.txt in the same directory, must be <0>.

15Example (R-Car V3H):
16
17	pcie-phy@e65d0000 {
18		compatible = "renesas,r8a77980-pcie-phy";
19		reg = <0 0xe65d0000 0 0x8000>;
20		#phy-cells = <0>;
21		clocks = <&cpg CPG_MOD 319>;
22		power-domains = <&sysc 32>;
23		resets = <&cpg 319>;
24	};
