ROCKCHIP COMBO PHY WITH NANENG IP BLOCK

Required properties (phy (parent) node):
 - compatible : should be one of the listed compatibles:
	* "rockchip,rk3568-naneng-combphy"
 - reg : the address offset of grf for combo-phy configuration.
 - rockchip,pipe-grf : phandle to the syscon managing the "pipe general register files"
 - rockchip,pipe-phy-grf: phandle to the syscon managing the "phy general register files"
 - clocks : phandle + phy specifier pair, for the input clocks of phy.
 - clock-names : input clocks name of phy.
 - resets : phandle + reset specifier pairs.
 - reset-names : reset names of phy.
 - #clock-cells : should be 1.

Optional properties:
 - assigned-clocks : phandle of refclk.
 - assigned-clock-parents : parent of clk_xxx_osc or clk_xxx_div.
		 Refer to clk/clock-bindings.txt for generic clock
		 consumer properties.
 - rockchip,dis-u3otg0-port: when set, disable the u3 root port of otg0 host.
 - rockchip,dis-u3otg1-port: when set, disable the u3 root port of otg1 host.

Example:

combphy0: phy@fe820000 {
	compatible = "rockchip,rk3568-naneng-combphy";
	reg = <0x0 0xfe820000 0x0 0x100>;
	#phy-cells = <1>;
	clocks = <&pmucru CLK_PCIEPHY0_REF>, <&cru PCLK_PIPEPHY0>;
	clock-names = "refclk", "apbclk";
	resets = <&cru SRST_P_PIPEPHY0>, <&cru SRST_PIPEPHY0>;
	reset-names = "combphy-apb", "combphy";
	rockchip,pipe-grf = <&pipegrf>;
	rockchip,pipe-phy-grf = <&pipe_phy_grf0>;
	status = "disabled";
};
