6*4882a593SmuzhiyunRequired properties:
7*4882a593Smuzhiyun- compatible: "renesas,r8a77980-pcie-phy" if the device is a part of the
8*4882a593Smuzhiyun	      R8A77980 SoC.
9*4882a593Smuzhiyun- reg: offset and length of the register block.
10*4882a593Smuzhiyun- clocks: clock phandle and specifier pair.
11*4882a593Smuzhiyun- power-domains: power domain phandle and specifier pair.
12*4882a593Smuzhiyun- resets: reset phandle and specifier pair.
13*4882a593Smuzhiyun- #phy-cells: see phy-bindings.txt in the same directory, must be <0>.
